How to hack SFC.DLL in Win2000.
Open SFC.DLL with XVI32.
Search for the hex byte sequence: '83 F8 9D 75 07 8B C6'.
You want Windows to treat ANY value in SFC as "disabled," so replace
83 F8 9D 75 07 8B C6 with B8 9D FF FF FF 90 90
Obviously, if you do this, you don't need to write the SFCDisable registry value anywhere else.
Now save the file and exit the program.
Be sure to run MODIFYPE on it!
