I'm trying to edit a registry key (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\AGP) but the registry won't let me create a new value, it says that the key is in use by a process.

I've tried:
- .reg file
- .inf file
- safe-mode
- safe-mode basic video
- using reg from the command line (Start > Run > CMD)


I tried msconfig too but there's no boot.ini or autoexec.bat anymore so no dice. :banghead:

Any help?:cry:

I'm trying to add the PCIid for the ULi AGP8x Controller. For some reason it isn't registered by default.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\AGP]
"10B95246"=hex:80,00,00,00,00,00,00,00

It's a fresh install so I don't mind if it breaks.


EDIT: Bart's PE doesn't pickup my keyboard for some reason. Testing with UBCD4W

Software A lot.
Benchmark Scores Its fast. Enough.
Now malware that reaches your user level rights can effectively fuck your computer.


Only grant permissions one sub directory of windows at a time, or boot to a windows disk with regedit added to the sources directory.
