Copying over i8042prt.sys, or msi8042.sys in W2K build greater than 2039

Problem:

I'm trying to drop in a new keyboard driver that will work with SI on a build of W2K greater than 2039. Everytime I copy it it looks like it's been copied over, but later on someone overwrites it back to it's original value! What's going on?

Resolution:

You need to either reboot the system into safe mode, do the replace of the keyboard driver (i8042prt.sys) in safe mode, and then reboot into normal Windows 2000, <or> change the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\SFCDisable to 1, reboot, *and* have the system debugger (windbg) running when you reboot.

Also, On Windows 2000 builds 2039 and later, you must have a kernel debugger attached to the system to use SFCDisable=1 or SFCDisable=2. To test private binaries, you will have to attach a kernel debugger to the target system.
