How to disable WFP (made easy)

When trying to change winlogon.exe, Windows just replaces it with its own version without prompting (which would allow one to prevent this). Only way to bypass this problem is to disable Windows File Protection (WFP).

Here's the basic steps for Windows XP SP2 only!

  1. Copy file C:\Windows\System32\SFC_OS.DLL to a folder and rename it to SFC_patch.DLL
  2. Download Free Hex Editor (493KB) and unzip file. Hex editor is called XVI32.exe which you must double-click
  3. From Hex Editor, open file SFC_patch.DLL. Press Ctrl-G (for GOTO) and set as follows:



    On OK, you should get:



  4. At offset 0xECE9 (as done in Goto), change hex 33 C0 40 to hex 90 90 90 and save the changes. Hex Editor should show:



  5. Create 'sfc_os.reg' file with following contents:
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
    "SFCDisable"=dword:ffffff9d

  6. Copy file SFC_patch.DLL to folder C:\Windows\System32
  7. Double-click sfc_os.reg file to make the registry change
  8. Boot system using Windows Installation CD (this takes a while)
  9. At Welcome screen, press R for Repair
  10. You will be prompted for which OS. In most cases, there's only 1 OS installed. Press 1 then Enter
  11. Windows will prompt you for the Administrator password. In most cases this is not set so just hit Enter
  12. You are now in the Recovery Console and the command prompt should show "C:\Windows"
  13. Enter these commands in sequence:
    • cd system32
    • ren SFC_OS.DLL SFC_OS.DLL.bak
    • ren SFC_patch.DLL SFC_OS.DLL
    • exit

  14. After 'exit' command, your system reboots. Remove Installation CD

WFP is now disabled!
