Patches to improve and speed up network connections, the Internet and browsers

Note:  I leave in two post links at the end of a single file of 8 KB, patches for the use of this tutorial. The names marked in red , have the same file names that come within the comprimido.Así know which are used for each.
Increase the performance of your Internet connection by adjusting Windows registry settings, optimize the use of browsers decreasing the time required to load web pages, tune the system to the maximum speed for more surfing the net, all above allow the patches on this page.

What are the patches for Windows or browsers?

Computer patches are only modifications made ​​to the original files of an operating system or application software, either by the author or original equipment or by a third party, always with the good intention of improving the performance and characteristics of product. 
The most common is that the updates made ​​by the manufacturers, come in packages provided by them, sometimes automatically, but we can not underestimate the improvements made ​​by third parties generally are ideal in environments and conditions not provided by the authors such as slow network connections, interaction with other programs, hardware or equipment used with incompatible, and so on. 
Here is a simple collection of the most popular and effective patches to download, which can be used in Windows to increase performance and speed Internet connection. 
Ideal for everyone who uses an Internet connection than a broadband, but still useful for anyone wishing to raise the performance it has. 
also some for Mozilla Firefox and Internet Explorer.

Patches to improve performance in Windows Internet

 Optimize registry settings for TCP / IP

Generic patch, only for Windows XP and Windows 2000. 
To install unzip the file, run it and restarted for the changes.
Tweak_2k
Operating System:  Windows 2000/XP/2k3

Use the patch depending on your operating system, no changes will be effective until you restart the system.
Webtweak_9x
Operating Systems Windows 95/98/98SE/ME
Webtweak_2k
Windows 2000/XP operating systems

Fix DNS errors in the cache of Windows XP

Windows caches the IP addresses of known sites to ensure faster access to them, but when a temporary fault in the DNS server, still clinging to the old configuration, but seconds later the server is reset. This results in the inability of the connection. 
You have two options:
1 - Manually adding in the command window:  ipconfig / flushdns
2 - Restart the PC
To resolve this permanently use the following patches:
winxp_dnscache
winxp_dnscache_undo to revert to previous values

Improve bandwidth in Windows XP

Windows XP retains 20% of the available bandwidth, in order to execute special applications. The "retention" is produced by the packet scheduler called QoS (Quality of Servi
However, for private users, who only have a PC at home, QoS is not a necessary function, but rather the opposite. 
Windows XP reserves 20% of the bandwidth if the user cancels the QoS function. You can also choose to uninstall the QoS Packet Scheduler if we have no local network.
1) Start, Run, type in: gpedit.msc 
2) You see the Group Policy, go to Settings Team. 
3) Administrative Templates 
4) Network (Network) 
5) QoS Packet Scheduler 7) Double click on Limit the width of reserved band 
6) to enable it and put the 0% limit bandwidth. 
7) Apply and OK (Go into network properties and check that you are marking the QoS Packet Scheduler.)
Alternative method by editing the registry. Modify the following key.
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ psched \ NonBestEffortLimit = 0
Or use the following file  Increase bandwidth
You must restart to apply changes 
The same applies to Windows XP to Vista

How to reinstall TCP / IP in Windows XP

It may be that you are compelled to reinstall the TCP / IP, it can sometimes be the only way to resolve conflict
In Windows XP this box unchecked to disable this protocol, the most appropriate solution is reset by NetShell.
To do this type in the command window and press Enter:
netsh int ip reset c: \ resetlog.txt
resetlog.txt is a text file where you write the changes.

How to reinstall TCP / IP in Vista or 7

Netsh interface IPV4 RESET

Increase the performance of the LAN (Local Area Connection)


Disable  Network Task Scheduler

This setting disables the search in local area teams scheduled tasks. Reduce the long wait when you open the network folder. To apply this setting downloads and executes the following files:
sg_lan_speedup.reg
undo_sg_lan_speedup.reg

Increase value of the job buffer

(Reduce the delay in networks)
In LANs can experience some delay with the default value of the buffer: (4356 decimal). 
The range of this parameter is between 1024 and 65535 bytes. Tests have shown that the standard networking best option is a value of 16384 (decimal), this only applies to LAN and helps slow browsing large directories.
To change this setting in the registry navigate to:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ LanmanServer \ Parameters
Add value  REG_DWORD  named  SizReqBuf  , set the value to 16384 or even higher, reboot to apply the changes. 
Here is the Microsoft article that describes how  MS KB Article 320829

Increasing the buffer network redirection

(Best performance in networks)
If you increase the number of buffers therefore will increase the speed of the network. Each extra thread you add will take 1KB of additional memory, but only if your application is using it now. 
To configure additional buffers and threads, edit:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ LanmanWorkstation \ Parameters
Modify or add value type  REG_DWORD  for:
MaxCmds = dword: 00000064  the range is between 0 and 255 and the default is 15. Bring to a higher value for example 64 to start.
MaxThreads = dword: 00000064  put it at the same value MaxCmds.

Not sharing in My Network Places.

Speed ​​up Windows Explorer and network browsing by stopping automatic search in  My Network Places .
By default  Windows 2k/XP/2k3  ​​access information about the shortcut to the folder  My Network Places , causing system slowdowns, every time you open a remote shared folder, Windows will automatically add another shortcut to  My Sites Red  making the problem worse. 
To fix this go to:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
Add a new DWORD value: NoRecentDocsNetHood = 1  establécelo to 1 to disable remote file shares that are added to  My Network Places .
For additional information read:  MS TechNet - NoRecentDocsNetHood

Patches to improve performance of web browsers


Patches for Internet Explorer


Internet Explorer 8 and 9 faster with a simple trick.

This little trick Internet Explorer 8 runs faster or 9 users of Windows 7, simply by registering a DLL (ActiveX Interface Marshaling Library). 
For that runs Start typing CMD or Run: CMD and when black window opens MSDOS type or paste:  regsvr32 actxprxy.dll
's all, restart and you will notice the difference immediately. 
If you use Windows Vista you have to use "Run as Administrator".

Increase the number of simultaneous connections.

According to the rules of the HTTP protocol, only a limited number of connections are allowed to the web server. Today with the existing broadband connections increase profits and increase your productivity. 
To increase the number of connections adds the following registry entries:

In  Windows 9x/ME/2k/XP
Access to the registry editor REGEDIT.
Start> Run, type regedit and press Enter. 
Find the following branch and add the following DWORD value:
HKEY_USERS.DEFAULT \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet


In  Windows Server Vista/7/2k8
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ MAIN \ FeatureControl \ 
FEATURE_MAXCONNECTIONSPER1_0SERVER \ explorer.exe = 8  (DWORD Default: 4, recommended: 8)FEATURE_MAXCONNECTIONSPERSERVER \ explorer.exe = 8  (DWORD, default: 2, recommended: 8)

Another alternative is to use Windows 9x/ME/2k/XP and apply the following patch:
Webtweak_2k

Disable the parallel processes in Internet Explorer.

Internet Explorer 8 and 9 adds a new tab system processes, to increase stability and performance. 
For those with little RAM, they should disable this function and thus prevent the creation of a number of parallel processes on the PC called :  iexplore.exe  that you see in the Task Manager, slowing navigation and memory consuming. 
For that go into the registry and creates the following  new DWORD value :

For Internet Explorer on Windows XP [HKEY_CURRENT_USER \ Software \ Microsoft \ Internet Explorer \ Main]"TabProcGrowth" = dword: 00000000


For Internet Explorer andn Windows Vista or 7 [HKEY_CURRENT_USER \ Software \ Microsoft \ Internet Explorer \ Main]"TabProcGrowth" = dword: 00000001

Mozilla patches Firefox


Parallel requests (pipelining requests) 

This is equivalent to patch Internet Explorer, follow the instructions:

1. In the Firefox address bar type:  about: config
2. Locate and change the following values ​​by double clicking them:
network.http.pipelining = true  (default is false) network.http.proxy.pipelining = true  (default is false)network.http.max-connections = 24  (default is 24) network.http.max-connections-per- server = 10  (default SS8)network.http.max-persistent-connections-per-proxy = 8  (default is 4) network.http.max-persistent-connections-per-server = 4  (default is 2) network.http . pipelining.maxrequests = 10  (default is 4)





3. Optionally you can set the following values:
content.notify.backoffcount = 5 
ui.submenuDelay = 0

Reducing initial delay (Delay Reduces Initial Page) 

By default Firefox 250ms wait before starting to draw the page, to reduce this range and get them to display pages faster, do the following:
1. In the Firefox address bar type:  about: config
2. Anywhere right click and make New> String or New: string 
3. Name the string:  nglayout.initialpaint.delay  (no spaces) and set the value between o and 50 (in milliseconds).

Advanced settings for Firefox.

Below you will find settings to reduce the time needed to load the pages. Some of these settings do not exist in the Firefox configuration, you need to create the values ​​if you want to experiment with them.
content.interrupt.parsing  Recommended value = true. content.max.tokenizing.time  Recommended value ~ 2250000.content.notify.interval  recommended value ~ 750000 content.notify.ontimer  Recommended value = true.content.switch.threshold  Increasing the value will make the browser more stable at the expense of load time of pages.browser.cache.memory.capacity  Memory in KB reserved for caching images, values ​​vary according to the RAM available.
In the following link you can find more information on Mozilla's website, of all the entries in  about: config  to their defaults.

As disavow your PC with iTunes if your system has Fallen

Well, hello boys. How about?, Well, is that I have formatted the computer, unfortunately, after 2 years (according to AIDA32 has since 2010 without formatting), and clearly after reformat, install itunes, up there all right, then you I say yes overwriting the library of music with my ipod (I have not saved data), up there all right, because I did not need music, then told me to copy out the apps to your computer and authorize your computer , and SURPRISE!, turns out I spent an authorization of a team that was already formatted, or that I have 3 computers and only to allow two computers are already authorized, the first was the pre-formatted, and the second was to after it is formatted, and clear, and you get two inches of noses, the apple obsession to make everything perfect, well, in this tutorial and learn to override a computer that is damaged, and therefore have to format the computer to fully recover the computer, in this tutorial, learn how to enter safe mode, so you can boot to itunes, and if it fails, learn other ways, well, go with it :
ATTENTION, ATTENTION, VERY IMPORTANT TO ALL THOSE RESPONSIBLE FOR COMPUTERS AND ALL THOSE INVOLVED TO COMPUTER MODULE INCLUDING THOSE WHO ARE IN INTERMEDIATE FP THAT ARE IN FIRST AND SECOND: Before you reformat your computer, this process is important do so to the apple do not throw the authorization of the team, and thus do not have to contact apple for you to remove the authorization of the team, so before you continue formatting the computer, please carefully follow all the steps in this tutorial before carrying out any repair that is dedicated to format the computer, or if, Apple will pull you so automatic authorization, and if for example you already have 4 computers authorized, with the fifth and you have exhausted the quota, and if you can install apps from the device in its  App Store , but you can not synchronize or install apps from itunes because this program you will deny it completely.
WARNING, WARNING, WARNING important FOR USERS WHO HAVE INSTALLED LINUX WINE FROM ITUNES: If your operating system is Linux and you have been broken, we're sorry but there is no way to override the computer if the graphical environment is damaged due that linux has no fail-safe mode as windows, linux has the recovery mode that allows you to do maintenance, but from the command line, and to undermine the team, you need a graphical environment for obligation, so the only two ways out there to disallow a team from itunes if you live only linux is or use the button to "withdraw all authorizations" or call Apple Support to address the subject of withdrawing the authorization of the team 've formatted, there is no program until you remove the authorization on the computer of a newly installed linux
ATTENTION, ATTENTION: The other way we're going to count, which is to withdraw all authorizations for the computer, according to the apple, you can only use it once a year, more or less similar to the general rules of the social network Tuenti, that only lets you change your profile name twice a year, if you've exhausted both times, you'll have to wait 365 days from the date on which you typed the name of your profile, as this is the same, if you give to "prohibit all", this function may no longer be available to within 365 days from the date on which button you have given to disavow all authorizations, also, this button might not appear if you are authorized under 2 computers
good, and now these important warnings, let's go through the tutorial, but not before having three important elements to be mentioned in this tutorial, which are "safe mode" "safe mode with networking" "safe mode with symbol system ":
  • Safe Mode: fundamental and indispensable tool for all repair, safe mode is a "special status" of windows, where only the essential start as some drivers, a few windows services, in short, all the essentials to boot windows, this mode is used to carry out maintenance and repair from a clean and without error in windows, this way you can for example run System Restore to return your computer to a time when working properly, install programs that you prevent install from the normal mode, install drivers, uninstall drivers, you can for example, if you get an error trying to repair windows, etc.. formerly in Windows 9X, to access the menu with the modes, you have to give the control key, to access this mode, and thus formerly was called "Safe Mode", later changed the name to "mode safe "since 2000, and also change the button is to enter the mode, which has now changed to the F8 key, but still doing the same function as in operating systems prior to windows 7 and windows 7.
  • Safe Mode with Networking: same tune that the definition above, but now load the network drivers needed to access the Internet and for example, update the database of your antivirus to scan your computer from this mode.
  • Safe Mode with Command Prompt: same hoax in the other two, but now will not boot environment (or interface) graphics and console boots the system, you can execute the orders of maintenance, repair and management team from an MS-DOS session, this order is only for advanced users who know yuo MS-DOS.
Well, now that I have explained the ways that exist in Windows, proceed as below to disavow that the computer if your computer is broken and can not access windows, if you can access, perfect, go to the itunes and ignores the the fail-safe mode, if you can not access windows, follow all the steps of the tutorial we will say here:
  1. before formatting the computer, if you are in your workplace, first you have to ask the employee if you have an Apple device in his possession, and if you usually bring to the job frequently, if yes, you must withdraw the authorization before formatting your computer, but you could throw the authorization and even worse, if you have five licenses and has exhausted the quota of permits, iTunes may terminate the synchronization of the items you have purchased from the app store, apps unless patched with Crackulous ( if you have installed the AppSync, of course), and only will be able to transmit the files to the Apple device if the device is unlocked (ie jailbroken) through SSH (to see how to install SSH continues to  this ) so the first step, before you start make sure that the computer owner has a device if that device apple and apple will often usually bring to the workplace, you're home, clearly ignore this step because clearly you have your Apple device.
  2. then after making sure you have an Apple device, and now seen the error happens to the computer operating system, if a grave mistake which you windows operating system and can not properly access the graphical environment, we will start the computer but press the F8 key many times, will press until the screen display modes that exist to repair computer repair:

  3. when the screen display modes repair the computer, select "Safe Mode with Networking" using the arrow keys up and down, and when we select, we will enter.
  4. then on the next screen is the boot loader of the operating system, give enter to continue booting in safe mode with network drivers enabled:

  5. the system automatically started up in safe mode, we expect to fully boot the system from this mode, which of course should not take much to start, because the safe mode, only run the bare minimum to boot windows, so wait a few seconds to boot, do not hurry.
  6. when starting the failsafe mode, we show typical login screen system, where we have to put our username and our password, or user and administrator password, put it, and give the button the right arrow (both XP and 7):

  7. then on the next screen (really you're already in Safe Mode because it puts up), if you start System Restore will propose to fix the error you have on your computer or continue booting the failsafe mode, as I've tried everything and you have to reformat the computer, we give you if:

  8. once on the desktop in that way (following catches are to be made from normal mode, because logically in Safe Mode, you have to work if or if) we will have to find itunes so we're going to start-all programs (or programs)-itunes-itunes.
  9. after starting itunes, which is this screen here:

  10. after being on itunes, we give "store", will display this menu:

  11. then it must be given to "withdraw authorization of this team":

  12. then in the next screen, type the email address and password associated with your account, this is your screen:

  13. then after giving "withdraw authorization", iTunes will connect to Apple servers, and automatically request to the server itunes withdrawal of this approval, we will see in the next screen that says you are connecting to itunes store, it is that authorizations will consult and to withdraw the authorization of the team:

  14. then tell the message "has withdrawn the authorization of the computer properly," says that if you notice, congratulations, you just deauthorize iTunes on your computer, and therefore you can now format your computer with confidence.
If the computer still does not start, but we can try another alternative, of course linux is not going to mention in the tutorial, because this operating system has no fail-safe mode and in windows, and wine may be in a disk file virtual disk, or to a file where it can not run the file iTunes.exe, so linux, ignored, which we will use below is a compilation of all kinds of programs, equipment information, to safeguard the data and repair and maintenance and diagnostic equipment in general maintenance of certain parts of the hardware, like hard disks, called hiren's boot, the hiren's boot is the basic tool that thou must have all the repairmen when repair your equipment, because What you can know when the time needed to repair a computer, this mega-compilation includes a live-cd operating system that is a mini-Windows XP, an operating system on the CD, from which you can access all applications included in this compilation in graphic mode (there are also utilities based on MS-DOS), but is valuable because it can save data from a computer that has damaged the operating system so that formatting the computer does not lose the data, well, in this tutorial learn how to boot the liveCD and even better, iTunes.exe boot from the liveCD and so withdraw the authorization of the team in total comfort, here we go:
  1. the first is to access the BIOS and make sure the boot sequence as first CD-DVD, so a first step, access the BIOS, which is usually accessed with F1, F2, ESC, DEL.
  2. then have to locate an option to put "boot SEQUENCE" or boot sequence, so consult the manual for your motherboard section where you put the boot sequence and follow her.
  3. then after accessing the section corresponding to the boot sequence, first change it to CD and then the disc, you know, following the motherboard manual in full, but I tell you that normally the + or - button , F5 and F6, and so on. also points out that the BIOS are all in English, so you may need to pull the dictionary to translate some words you do not know, so if necessary, pull the dictionary.
  4. after exiting the BIOS, saving changes (F10 or F11 or F12), enter the hiren's boot CD on the computer where you want to repair it.
  5. then after you main menu will hiren's, select mini-windows XP.
  6. wait a while to boot up and within minutes will take you to the desktop.
  7. But once on the desktop, the desktop is Hirens this screen we see here:

  8. the first will be running the network, since to make the task of withdrawal of approval, we need internet connection on your computer, so press "network setup", this program included in the hiren's configure automatically the network, and installed the drivers on the live CD of XP, so we double click:

  9. is then only wait for it to finish booting the program, and make the appropriate operations to enable internet on this computer, wait a bit to complete:

  10. then after you close the program auto-configuration, we will have enabled the network cards and therefore have internet right now, we can see in the taskbar, where the bottom right of all, this is its icon:
  1. then is to open the iTunes program from your location, so we give "my computer":

  2. subsequently the itunes is in C: \ Program Files \ iTunes \ iTunes.exe, go to the itunes folder in program files and this is the screen should show you:

  3. then you start the program and then follow the first tutorial steps 9 to 13, to withdraw the authorization of your computer and reformat the computer so freely.

withdraw all authorizations for all the computers you have authorized apple ID
well, this possibility will have below so wonderful to have these apple, itunes currently there is a very interesting button in the status of the account that allows you to withdraw all licenses for all computers from anywhere in the world, this button addition is useful for Linux users, is useful in case you do not have time to withdraw the authorization, so that you can remove easily and without effort, but we have to agree that this solution need to use it only for emergencies, and this is not an authorization removed, remove all authorizations, making it possible that if you have authorized a computer that is not formatted, remove the authorization and have to re-authorize, is also useful in the workplace, if the head, after making a dismissal for whatever reason, do not let go of the workplace to disallow computer nor lets take it home, then you can override the computer by "remote control", and so the ex- employee of the company is coming to save the company and disallow the computer from your company, but it is mainly useful if you want to disallow computer to access can not so easily to him, it can disallow perfectly, well, now explained this , we proceed with the tutorial, but first consider several caveats that must be taken into account: 
ATTENTION, ATTENTION. Important WARNING TO USERS LINUX OPERATING SYSTEM: remember that this is the only way to deauthorize your computer with Linux, and that at present there is no way to remove an authorization from the linux operating system that is damaged, so if you say that if you can remove the authorization to a computer running linux broken to know that what you say is a lie, because there is no linux failsafe mode, so there is a recovery mode that allows you to make maintenance and repair but from command mode, and to withdraw the authorization of a computer running Linux, you use the graphical environment mandatory, so if you have a Linux system, read carefully the steps of the tutorial and follow it to the foot the letter, because this is the only way to remove an existing authorization on a linux system, so read on and find the solution halfway. 

ATTENTION, ATTENTION, SUPER-IMPORTANT: Remember that according to apple the button can only be used once a year, so if you have exhausted the quota, you can not use this button and the only solution you have left is to contact apple, so you can withdraw the authorization, but that if, if they ask if the device is unlocked (ie jailbroken), tell them not to unlocked so you can better, you know that Apple does not support the word jailbreak, the proof is the attempt to censor the word jailbreak iTunes ( see the news here ) 

ATTENTION, ATTENTION ALL RESPONSIBLE FOR THE COMPUTER SECTION OF ALL THE WORK AND RESPONSIBILITY OF HARDWARE AND OTHERS INVOLVED IN THE COMPUTER AND COMMUNICATIONS INDUSTRY: If you see an incident, it does not matter if by mail, a web application for management of stock (some companies have it) or by other programs, that there is a bug in the iTunes relaccionado with synchronization of the elements or you have to remove all licenses for all computers associated to that apple ID you know that before you go and disavow all computers associated with Apple ID, you got to ask that person to access your account from a computer at work, because where we're going to access, we envision personal and private data of people, in addition to access other accounts without permission is not good, so before attending the incident, contact the site that created the incidence for permission to overrule all computers in the apple ID, because people do not like being looked at personal data of other "outsiders", besides that you can sit wrong and could be very angry, so the incidence before attending talks with the user and say that if you get permission to withdraw the authorization of your apple, but does not give you permission, you propose to do so under the supervision of another user (ie the owner of the account is ahead) or tell the steps in detail, and so the landlord will do and will be now resolved the issue. 

ATTENTION, ATTENTION: I have researched what the stream of user accounts in the domain of Crackulous tutorial ( go here ), and is that if there is an authorization of another domain user and you also authorize the computer, these authorizations are crossed (ie collide), preventing you from power transmission and synchronize the device apple from your workplace, then the only solution there is to solve the problem, create a local account to gain access to itunes so completely, we'll see in upcoming installments.

well, and once those warnings, proceed below to tell all the steps for the withdrawal of authorizations for all computers associated with Apple ID, go further with the tutorial:

  1. The first step is, if you are in the workplace and the employee or employee no longer with the company, you have to look at the calendar, phone book, resumes saved, etc.. the phone number of the person or in this case, the skype or mail from that person, (for mail, messenger best used), plan to contact that person and tell the steps, through the medium of communication that is, it also use the chat function of social networks, is essential for contact with that person easily, you're home, you do not need this at all, after contact with the employee or employee, tell him to follow these steps to disavow all computers associated with apple ID.
  2. after contact with the employee or have the computer you desautorizaremos authorizations associated with each computer that has an Apple ID, iTunes pluck below or from the desktop, the installer automatically creates an icon on the desktop (windows only 7) or from Start-Programs (or All Programs)-itunes-itunes, this is how you do:

  3. later after access to iTunes, this is your screen:

  4. Below we access the official Apple store (the app store), unless the version for your computer is itunes itunes store, we click on it, and this is the screen that should appear:

  5. if you get it to "identify", that is you have to log in with your user account and password, so it must be given to "identify" and then enter the email address and password, then you have to give " connect, "and we are already in the account.
  6. later and on iTunes store, but is to give the email address of the account, just the item you have to find is here (indicated by a rectangle):
  7. later we will have to enter email and password, this will put the apple, most of all for security, so if someone wants to snoop around your computer, you have to enter your email and password, also remeber that the data account showing your personal details, so more reason to put this apple, this is the screenshot:

  8. then on the next screen, which logically will not show for the personal data that do not have to show on the Internet, you have to give this button you indicated in the screenshot to disallow all computers including your computer, this is the capture :

  9. itunes then contacted with the apple server, and disallow all computers success, if you already has confounded, and have free way to format and install your operating system successfully.
well, up here the tutorial, hope you had fun with what you have us and all, to all repairers that I hope you like this tutorial to ensure complete success in the format and installation of your operating system and I expect the method to solve this well you have done any good, and nothing, a Parceros SALU2 from Colombia.
