Vista TCP/IP AutoPatch doesn't work anymore

Vista SP1 here.
As you know, Windows limit half-open connection to 10, which slows down any P2P program.

When the limit is hit, You will recieve a Notice in Event Viewer Saying:
EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.
This means Vista Has maxed out our connect attempts.

There are patches for XP, and Vista, which actually work around that limit.
Vista patch: http://www.softpedia.com/get/Tweak/Network-Tweak/TCP-IP-Limit-AutoPatch.shtml is a simple script:

Code:

@echo off
TITLE Windows Vista Event ID 4226 AutoPatch and UAC Disabler
echo.
echo Windows Vista Concurrent TCP/IP Connection Attempt Limit Auto Patcher
echo Event ID 4226 Fix for 32-bit version of Windows Vista 
echo and UAC Auto Disabler
echo.
echo.
echo Made by defcon http://securevista.net
echo.
echo.
echo Do you Want to Disable UAC?
echo.
echo Press Y to continue or Press Ctrl-C and answer Y to terminate
pause
echo Disabling UAC....
reg import uac_admin_off.reg
echo UAC Disabled.
echo Install TCP patch? Press Y to continue or Press Ctrl-C and answer Y to terminate
pause
takeown /f %Systemroot%\System32\drivers\
takeown /f %Systemroot%\System32\drivers\tcpip.sys
icacls %Systemroot%\System32\drivers\tcpip.sys /grant  "%username% ":f
echo y | cacls %Systemroot%\System32\drivers\tcpip.sys /g  "%username% ":f
netsh int tcp set global autotuninglevel=disable
copy %Systemroot%\system32\drivers\tcpip.sys %Systemroot%\system32\drivers\tcpip.original 
echo.
echo Original tcpip.sys driver has been renamed to  "tcpip.original" in its original folder.
echo.
copy tcpip32.sys %Systemroot%\system32\drivers\tcpip.sys /y
reg import Vista_TCPIP_Limit_70000.reg
echo.
echo *** TCP/IP Connections are now at 70000
echo.
echo.
echo.
echo *** Save all work, will ask if you want to reboot to finish installation.
echo.
echo Reboot? Press Y to continue or Press Ctrl-C and answer Y to terminate
pause
shutdown /r

which basically replaces existing tcpip.sys file with a new one, where default limit (which can be changed) is set to 70000.

The above patch worked perfectly fine for me for several months, and I didn't have any EventID 4226 errors.
However, after last Tuesday updates EventID errors came back.
Surely, some update did something to tcpip.sys file, setting the limit back.

I thought, that simply re-applying the patch will fix things back to normal, but, no.
When I apply the patch, it needs to restart Windows, but after restart, Windows reports unspecified error, and runs System Restore.
After repair, Windows starts perfectly fine, but obviously patch is gone, since I can see EventID 4226 error back.

Any thoughts?

 

Just in case, someone is interested, new patches have been released, and they work.
