SFC /SCANNOW Command - System File Checker

That's what bothers me, Brink,
The fact that after our earlier discussions in this thread, last weekend I did a repair install on my machine, did not reinstall all the apps i previously had, and yet this 'corrupted system file' recurrence.
Is it possible that I am starting from a position of file corruption in my 'family pack' DVD?
Can I use a friend's Win7 Home Premium (same edition) to repair install my machine and use 'my license' to validate?
Or can I extract the system files from my friend's OS and use that to repair mine.
Will still try your suggestion of trying option one of your tutorial, though.
These are the problems I'm currently having with my machine:
1. Unable to create system image backups
2. Of late, unable to update Win 7
3. Repeated intermittent crashing of all browsers (IE, Chrome, Opera, Firefox)
4. Crashing Windows Explorer, Com Surrogate etc.
5. Intermittent BSOD's (like clicking on a link in open web-pages)
6. Repeated 'corruption' of system files.
Appreciate your advice

Does anybody know what "PublicKeyToken = {l:8 b:31bf3856ad364e35}" is? Looking through Henfracar's attachment I noticed most of the troublesome files mention that particular item. I googled it, and it looks like it is tied into WMP and the Vista sidebar, but I don't really know what it is or what it does.

Hi,
Thanks for all the great info. I ran scannow a couple of times from within Windows 7 and twice more at the boot prompt. In all cases, scannow reported that it could not repair some of the files. I've extracted the cbs.log file to sfcdetails.txt as shown in the tutorial and was hoping someone more knowledgeable than me could help decipher it. BTW, I deleted all old entries in the file prior to today.

Thanks,
Mitchell

Hey Shawn,

Thanks for the quick response.

I followed the instructions on the link you included and made it to step 12 (copying the file from desktop to system 32 folder). I restarted the computer in Safe Mode with command prompt and entered the appropriate command to copy the dll file. Unfortunately, I received an error message "access is denied" when I tried to copy the file from the desktop to the system32 folder. I tried copying the file to another location successfully, so this tells me the problem is the system 32 destination folder.

I'm probably doing something stupid, but any help would be appreciated it.

Thanks again,
Mitchell

Hi Shawn,

Well, I did take ownership and set permissions, but for the wrong file. I did it for the file I extracted--not the file I was replacing. Duh. So, I did it for the correct file and was able to copy it using the command prompt at boot. Scannow produced another error, but this time I was able to decipher it and found it to be tcpmon.ini, so I went through the copy procedure again and finally was able to run scannow with no errors. Yay! Again, thanks for all your help.
