You never want to include files protected by the Windows File Protection (WPF) feature of Windows 2000 and later in your packages. Below is some configuration notes on controlling WFP from the registry:
All registry settings for WFP/System File Checker are located in HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon.
By default, only Administrators and System will be able to modify these settings.
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).
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).
