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.
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
- 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.
- 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.
- 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 yetor 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. - Can I manually install the patched tcpip.sys manually?
Yes. Checkout the manual installation guide.

is there a patch for vista tcpip.sys version
6.0.6001.22121?
March 1st, 2009 13:40
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.

I used the x64bit patcher 2.2 and the correct version, I followed the instructions to the letter, it TOTALLY SCREWED MY SYSTEM, un-installed loads of drivers and even McFAee virus protection, could not install anything on my system as it un-installed my installer packages! please please please take my advice if your on vista 64 bit stay well clear of this or you’ll end up reinstalling vista and wasting days putting your system back to noraml YOU HAVE BEEN WARNED!!

Everything worked fine and I set the limit to 50,000 in the registry editor but for some reason I am still getting the same error code in the event viewer. Should I boost the limit or what? I am doing this mainly for Soulseek and every time I search for something and I check the event viewer I get that error.
February 11th, 2009 12:12
I tried to install it and when it started I saw it said something about not being able to install all parts or something? Does this matter? 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.

Sorry guys… Just found out that you have to press enter and under Microsoft Windows Vista screen you press F8. Anyway, the ReadyDriver didn’t work. Or maybe I lost something here.

I installed the Vista tcpip.sys and UAC Auto Patcher v2.2 (my tcpip.sys is version 6.0.60001.18063) and now I can’t bott anymore. There’s no “Disable Driver Signature Enforcement” option after I press F8. I installed everything according to instructions, even the ReadyDriver thing. Can somebody help me out here? I don’t believe I’ll have to install windows X64 again because I tried this patcher…
Thanks

Hi,
For any unknown reason, I can’t retrieve any properties details and version number on DETAILS pane as on my Vista version (Hebrew-Ultimate) the required information is not presented at all!. Could you please guide me what should I do in such case? I’d appreciate a lot your reply directly to my mail address: apter@bezeqint.net as info is needed very badly. Thanks in advance for your kind attention and prompt reply.
regards, Rafi…

All I can say is THANK GOD for people like this who make these patches, I was going insane by just browsing the net with this dumb ass limit on vista, I want to swear my guts out because ive been using comps for around 20+ years, and have ALWAYS enjoyed the speed and freedom of networking, UNTIL DUMB ASS VISA!!!!!!!!!!!!
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.
