HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Add/modify the "SFCDisable" DWORD [REG_DWORD] Binary entry to read FFFFFF9D

By defaut, the binary reads "0000 01 00 00 00". I changed the value from 0 to 1, but I don't know about the binary value entry since it's screwy.

First import the reg file, rename "sfc_os.dll" in C:\Windows\ServicePackFiles\ , then rename "sfc_os.dll" in C:\Windows\System32\ & copy patched dll in your System32 directory. :D (File Version: 5.1.2600.2180)

Can't you just do it from safe mode, like if you're just swapping the uxtheme.dll? I dunno, just asking.

Yes you can, but this way is faster, you don't need to restart. :p

Have seen a few different ways of disabling WFP (ie swapping .dll and changing reg values).

Has anyone bothered to put a compressed sfc_os.dl_ into their i386 directory on the cd so it installs disabled?

Also, has anyone tried to add this to their winnt.sif unattended answer file? If so, is copying the modified dll necessary?

[systemFileProtection]

SFCQuota=0

SFCScan=0

SFCDisable=ffffff9d

By the way, this was found for Windows 2003 Server, not sure if it works with XP SP2.

It is still necessary to copy the modified dll, without it WFP stays enabled.

    • Thank you, for not reading the comments above and just reading the root comment... it is just like reading only the headline of an article.
    • I just teams to stop stealing the damn focus every time it starts or restarts after an update. Annoying as all hell.
    • Obviously new hardware costs more money. Never said you get new 2025 hardware for $266. You get new 2025 hardware for as little as $399 and only gets better with back to school sales. At the $499-699, there's some decent spec laptops with 16 GB RAM, and 1 TB SSD with better build quality than this lowest end ideapad.

    • Can you get a brand new (not refurb) device like this, but with 2025 hardware, for $266? Under $300? No? If you can, it must have the worst specs otherwise (4gb ram, 1366x768 12in lcd screen, 256gb spinning hard drive, etc.). Please show me this sub-$300 2025 laptop that is better than what the article shows.
