How To Disable Windows File Protection (WFP) in Windows XP SP2

This item should not be related to programmers, but it was very depressing when writing the driver. There is no way to replace the built-in driver of the system! Dig the ground three feet to find the way to completely close, paste it first (Note: Check the version of sfc_ OS .dll before use, this method applies to sfc_ OS .dll 5.1.2600.2180 ).

1. use ultraedit to open sfc_ OS .dll under the System32 directory (back up to the dllcache directory before opening), CTRL + G to jump to address 0xece9, and change 33c040 to 909090, (In fact, the original code is filled with NOP) and saved as sfc_patch.dll;

2. log out of another system and rename sfc_patch.dll to sfc_ OS .dll. Alternatively, use the fault console and enter the following command:
Copy % SystemRoot %/system32/sfc_patch.dll % SystemRoot %/system32/sfc_ OS .dll/y

3. restart Windows XP;

4. Open the Registry Editor and set the sfcdisable key value under HKEY_LOCAL_MACHINE/software/Microsoft/Windows NT/CurrentVersion/Winlogon to 0xffffff9d;

5. restart Windows XP.
