View Full Version : System File Checker / Windows File Protection - XP Pro

01-08-2004, 09:59 AM
I have a modified Windows system file in my machine, which I would like to stay there. However every so often (occasionally on a reboot) I get the Windows File Protection or System File Checker (I can't remember which) message telling me that a system file has been changed and would I like to insert my original Windows CD to change it back to the original.

I would not like to change it back, so is there a way to either update SFC/WFP to accept the new system file (preferable) or else turn the SFC/WFP off altogether (not so acceptable).

The system file has been updated in both system32 and in dllcache. Is there somewhere else I should have replaced it as well? Before my last reinstall (about a couple of months ago) I never used to get these messages, and I've been using the updated file for more than a year. This install was the first time I've installed using a slipstreamed SP1 XP install.

OS = Windows XP Pro SP1
Replaced system file = uxtheme.dll

Just thinking aloud here Mike..... Those 2 locations, system32 and dllcache are the only places as far as I know that have the protected system files other than the CD.

I suppose you could copy i386 folder to C: drive and then modify the registry to point there rather than the CD.
If you could compress your uxtheme.dll file to uxtheme.dl_ (I dont know how off-hand) and replace the one in i386, maybe you could fool system file checker into thinking it had replaced the overwritten one with an original?

Thanks for your suggestion Terry. I'll give it a try, but from what I understand, SFC/WFP looks at "system" files everytime it boots for the Microsoft digital signature, and when it doesn't find one it complains. I think it'll just complain again next time I boot up.
