Re: Another new feature(Self Healing) -- MIDRANGE-L

Larry,

This process is known as Windows File Protection (WFP). It was created to
save us from the problems associated with "DLL Hell". It's based upon the
premise that _nothing_ should replace a system file. Personally, I think
it's a good feature that works well.

However, if you really want to mix & match the system files on your machine,
then you can turn this feature off by changing the SFCDisable (REG_WORD) to
1 or 2. The various options for this parameter are:

SFCDisable (REG_DWORD)
0 = enabled (default).
1 = disabled, prompt at boot to re-enable (debugger required).
2 = disabled at next boot only, no prompt to re-enable (debugger required).

The keyord is located in the system registry at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Here are the other options that you can use to control the behaviour of WFP
(all are found in same registory location):

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.
FFFFFFFF = cache-protected system files on the local hard drive.

SFCShowProgress (REG_DWORD)
0 = System File Checker progress meter is not displayed.
1 = System File Checker progress meter is displayed (default).

SFCDllCacheDir (REG_EXPAND_SZ)
Path = local location of dllcache directory (default is
%Systemroot%\system32\dllcache).


Good luck,
