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.
