SUMMARY
All registry settings for Windows File Protection/System File Checker are
located in the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
MORE INFORMATION
By default, only users with Administrator or System rights can modify these
settings.
Registry Values
SFCDisable (REG_DWORD)
0 = enabled (default)
1 = disabled, prompt at boot to re-enable
2 = disabled at next boot only, no prompt to re-enable
4 = enabled, with popups disabled
NOTE : For options 1 and 2: Both of these options require a kernel debugger
to be hooked up for those options to become useable. If a kernel debugger is
not hooked up, Windows File Protection is not disabled.
SFCScan (REG_DWORD)
0 = do not scan protected files at boot (default)
1 = scan protected files at every boot
2 = scan protected files once
SFCQuota (REG_DWORD)
n = size (in megabytes) of dllcache quota (default is 0xffffffff or
approximately 300 MB)
FFFFFFFF = cache all protected system files on the local hard disk
SFCDllCacheDir (REG_EXPAND_SZ)
Path = local or network location of dllcache folder (default is
%SystemRoot%\System32)
NOTE : Network shares for the dllcache directory are no longer supported.
SFCShowProgress (REG_DWORD)
0 = System File Checker progress meter is not displayed (default)
1 = System File Checker progress meter is displayed
NOTE : The Windows 2000 source files location information is stored in the
following registry location and can be modified to point to the drive letter
of a volume that has an I386 flat folder of the installation files
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\SourcePat
h:REG_SZ::
and
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\SourcePath:REG_SZ::
where drive letter is the appropriate drive letter.
Example:
If the I386 directory is at C:\I386, the SourcePath value would be C:.
If the I386 directory is at E:\Directory\I386, the SourcePath value would be
E:\Directory.
After you restart the computer, WFP and SFC /SCANNOW uses the new source
path instead of prompting for the Windows 2000 installation CD-ROM.
