Download Vista tcpip.sys and UAC Auto Patcher to Increase TCP Connection Limit

Windows Vista TCP/IP (tcpip.sys) and UAC Auto Patcher is a simple batch command script that automatically replaces and overwrites original tcpip.sys in \Windows\System32\Drivers\ folder with a patched tcpip.sys version (included) that has been modified and cracked to unlock and remove the limit imposed on concurrent half open TCP/IP connection attempts that Vista can launch at any one time. Patching the tcpip.sys to remove the restriction potentially yields benefits or solves problems as below.

  • Event ID 4226 in Event Viewer that describes TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts (more info).
  • Slow browsing speed such as web page unable to load or refresh when using P2P applications such as BitTorrent (BT) clients and eD2K eMule client.
  • Improve torrent speed and fix slow or even not moving downloading and uploading speed when using P2P programs. (see how to optimize torrent speed in Vista)

Prerequisite to Use Vista tcpip.sys and UAC Auto Patcher

Microsoft has released plenty of versions of tcpip.sys, thus each different versions of Windows Vista TCP/IP and UAC Auto Patcher will work only on certain version of Windows Vista, depending on the variant of tcpip.sys installed. To check the version of tcpip.sys, navigate to \Windows\System32\drivers folder, right click on tcpip.sys and select “Properties”, and the version info will be listed in “Details” pane.

TCPIP.sys Version

Features of Vista tcpip.sys and UAC Auto Patcher

  • Automatically copy and replace tcpip.sys with patched version that unlock TCP/IP connection limit.
  • Set the maximum concurrent half-open TCP connection attempts to 50,000.
  • Disable User Account Control (UAC).
  • Disable Vista TCP Auto Tuning feature to minimize possible networking problems.

Usage Guide / Installation

Unpack and extract the content of the archive, and then run InstallPatch32.bat (for x86 system) or InstallPatch64.bat (for x64 system). Administrator rights elevation required.

IMPORTANT for 64-bit (x64) Windows Vista (RTM and SP1) and 32-bit (x86) Windows Vista SP1:

Windows Vista now require all kernel-mode driver or software to be signed with digital signature in 64-bit Vista, and all boot-start drivers must be embedded-sign with signature on both x86 and x64 versions of Windows Vista. Unfortunately, tcpip.sys is both kernel mode driver, and also boot start driver, and modify tcpip.sys will break the existing signature, making the patched tcpip.sys unsigned.

So when using patched tcpip.sys, users must press F8 at every Windows boot load. When come to Vista Advanced Boot Options menu, select “Disable Driver Signature Enforcement” to bypass driver signing check and continue loading Windows Vista, else there may be boot-failure. The process can be automated with ReadyDriverPlus.

Uninstallation

Run UndoPatch.bat to restore original tcpip.sys (provided you don’t delete the backup tcpip.sys.original), uninstall and remove concurrent half-open TCP/IP connection limit setting in the registry, revert TCP/IP autotuning level to normal, and re-enable UAC.

FAQ and Troubleshooting

  1. How to change the connection limit to other value?

    Users can change the limit to any value by navigating to the following registry key using Registry Editor:

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\]

    Locate “TcpNumConnections” registry value and change its value data to number you want.

  2. I don’t want to disable UAC, how to re-enable UAC?

    Run “Enable_UAC_Prompt.reg”, if you no longer want to patch tcpip.sys, run “UndoPatch.bat”. It’s also possible to use tool such as TweakUAC.

  3. After installing patched tcpip.sys, the following problem exists on system boots up whenever restarts:

    Windows Failed to Start. a recent hardware or software change might be the cause. To fix the problem:
    1. Insert your Windows installation CD & restart.
    2. Choose Language.
    3. Click “Repair…”

    File: \Windows\System32\drivers\tcpip.sys
    Status: 0xc0000428
    Info: Windows cannot verify the digital signature for this file.

    Long answer makes short is press “Enter”, or pressing F8 while system starts up, which will display Vista Advanced Boot Options startup menu. Then select to “Disable Driver Signature Enforcement”. See explanation above on usage instruction, and there is no workaround to this annoyance yet or use ReadyDriver Plus to permanently automate disabling of driver signature enforcement. Else, try out CrackTcpip.sys driver based limit bypass, or make use of fully automated Half-Open Limit Fix which makes used of test cert.

  4. Can I manually install the patched tcpip.sys manually?

    Yes. Checkout the manual installation guide.

    Hey guys. My tcpip.sys version isn’t listed here(6.0.6002.18091).

    However, do you guys think it would help to upgrade my Vista to Windows 7 (really pissed at vista)? And do I need the same language(version) on Windows 7 as Vista for it to work?

    Im grateful for any kind of answer. cheers!

    I believe with 32-bit Vista Business SP2 installed this guide no longer works. My tcpip.sys product version is 6.0.6002.18005
    Furthermore, I navigated to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\] but “TcpNumConnections” is nowhere to be found. Services\Tcpip6 didn’t contain that registry entry either.

    Okay, both 2.2 and 2.2a are getting similar results when I try them. I go to “InstallPatch64-18063″ and confirm it to go but it gives me a few errors. Right off the bat I get
    “ERROR: Not all data was successfully written to the registry. Some keys are open by the system or other processes”
    “ERROR: The system cannot find the path specified. The system cannot find the path specified. Successfully processed 0 files; Failed processing 1 files”

    So I might just be doing something wrong, but it doesnt seem to want to work.

If it does what am I supposed to do, run it again or uninstall it and run it again? Someone help me out, I kept reading about how this can majorly fuck up your computer and I kind of don’t want that to happen.

    Thanks a lot, I had always had weird problems with utorrent since vista, my download speed had reached up to 2 MBs but after extended downloading it went down to barely topping 5kbs. I thought it was because comcast was screwing me over when I used excessive bandwith, so I passed this tweak up, but I decided to try it durring one of my low times of downloading and after using it I have 10 torrents going @30+ up to 150 kbs at once.

    THANK YOU SOOOOOOOOOOOOO MUCH, my net is now 20+ times faster.

    I used v2.2 on 6.0.6001.22167, but the driver installer didont work for me, i think it was becasue it installed on wrong startup HD, i have more than one OS, but i just disabled the driver check on boot and it was fine.

    Hello,
    I wanted to try utilizing this patch to increase the number of concurrent half-open TCP connections. I was considering using Patch V2.2. However, I am reluctant because I checked my c:\Windows\System32\drivers folder and my tcpip.sys file and properties of that file and I have product version: 6.0.6001.18063. The text above and in some of the comments below apparently there is a product version: 6.0.60001.18063 and that is also what Patch V2.2 seems to be listed for. Notice the extra 0 character, mine is 6001 while others seem to be 60001. Is this normal, and should Patch V2.2 work on my 6.0.6001.18063 version or is my version different from the 6.0.60001.18063?

    Thanks for any help and advice.

    I have a strange problem related to ReadyDriverPlus, it worked at first, then here what happened, when the system boots, it shows two options, windows vista and readyDriver, the readydriver is set to the default selection, till here we are cool.

    afterwards, the menu appears again and the two options as well, NO Advanced menu appears, which leads the keystrokes to reselect the readydriver again, and ofcourse the system doesnt boot.

    does anybody encountered such a problem or know how to fix it?

    Worked like a charm

    Vista 32-bit, TCP/IP file version 6.0.60001.18063, Patch V2.2

    Thank you for all of your efforts.

    Safe Steps i used:

    1. Disabled all network connections.
    2. Followed the steps described at the top for patching.

    NOTE: ReadyDriverPlus is included within the patch zip file, so you dont have to download it.

    So it seemed like the setup worked for me, and I was able to check the registry and see that it was set at 50,000 connections, but for some reason I am still getting the Event 4226 warnings. Does anyone have an explanation for that?

    2.2a has some references to %systemroot%\sysnative which fail on my 64bit system… i changed those up… also i notice the older batch files update stuff in winsxs, and winsxs backups, wouldnt it be ideal to have the batch replace 18000, 18063, etc, in the active system folder, and the winsxs, and the winsxs backup folders, with the various corresponding tcpip.sys patches or is that not necessary?

    Hi,

    I’m trying the 18063 patch, I’ve used both 2.2 and 2.2a, but they aren’t working for me as it says “elevation required”.

    This helped me a lot!

    For Windows Vista Ultimate SP1 with tcpip.sys version 6.0.60001.18063 or 6.0.6001.22167 (Support both x64 and x86 Windows Vista SP1 – check the version of system tcpip.sys located in \Windows\System32\drivers folder, and run Install32-18063.bat or Install32-22167.bat for 32-bit Vista or Install64-18063.bat or Install64-22167.bat accordingly.)

    (That was based on my version of tcpip.sys (6.0.60001.18063)
    reboot, it autoselects the bypass in ReadyDriverPlus
    NOTE: It screwed up the first reboot only because I thought I had to hit the up arrow once on the menu, rebooted again and let RDP do it’s thing and now I have much seeding goodness with high connections/Max connections!

    It blows my mind that this is hard coded beyond a reghack. I have never had problems with content from this site. However, I am simply not comfortable with replacing the .sys.

    2.2 works on Vista x64 SP1 with all updates applied & F8 method of bypassing signature checks. I did not run your batch file, though. I simply copied over the patched 6.0.6001.18063 file and ran the 50K registry key and disabled tcp ip autotuning.

    2.2a doesn’t work. the files are all the same (same CRC) and the only difference is in the .bat file (System32 was changed into Sysnative). that wasn’t the problem in my case, i could install the 2.2 patch just fine (the files did get patched), the problem was, that the patched tcpip.sys file didn’t have any effect. i still got the 4226 event and my sites took “forever” to load. so, im guessing the problem isnt in the .bat, but in the tcpip.sys file

    I got similar problems as Rob did 2.2 doesn’t work. After I patched with InstallPatch32-18063.bat and rebooted my vista 32bit system. I get a bunch of errors in event viewer such as “TCP/IP Protocol Driver is not a valid Win32 application.” and I can’t connect to the internet until I unpatch it and yes I did select Disable Driver Signature Enforcement”.

    Hi there,

    I downloaded readydriver and installed it and it loads on boot but it doesn’t seem to have an affect on the driver permissions for windows.

    So… I did it manually, changed tcpip.sys to tcpiporiginal.sys and added tcp32-18000.sys to the drivers. Then did the registry patch. Well when I did it I could no longer connect to the internet and I get the message ‘the dependency service or group failed to start’.

    Has anyone else experienced this problem and does anyone have any idea how to solve it? To get back on the internet I just undid the patch but i would like to get it working.

    Cheers, Rob

    I have UAC set up the way I want it – please don’t fsck with anything but the TCP IP setting! Sure you give a way to re-enable UAC, but I have it set to some custom settings already, and this will probably blow all my work away. As I’m on Vista Premium I’ll have to install another app to get the options I want since group policy editor doesn’t exist.
