Windows 7: sfc/ scannow results show two 'cannot repair' files..

sfc/ scannow results show two 'cannot repair' files..

Hi there. Any help seriously appreciated! >>

Running 7hp x64 on a gaming laptop (asus g50v).

sfc has thrown up two errors that it cannot repair, and I have been trying for ages now to replace the corrupt system files with fresh downloaded ones, without success.

Firstly, am i right to be concerned about replacing these files? i don't know their true purpose - i haven't encountered problems in day to day use of the computer but am unsatisfied to see an error message... Can i leave the corrupt files alone or does the old adage 'a stitch in time saves nine' apply here?

The files are tapiperf.dll and autochk.exe.

I haven't even got around to trying autochk yet, as all my efforts have been concentrated on the first file:

I have successfully taken ownership of tapiperf.dll via an elevated prompt following instructions at this link: Take Ownership of file - Vista Forums, but when i try to do the next step of this tutorial, giving myself permission to alter the file, and enter 'icacls......... (etc)' it gives me an error message that 'no mapping beween account names and security IDs was done' and fails.

i have found the replacement file from another site, which is standing by on my desktop... but i just can't get the corrupted file to be renamed and put the new one in it's place (Side note: i want to rename, not delete, the original file as a precaution - i presume i can rename it back again if the new one stuffs up..)

What am I doing wrong here please? I can post the CBS log if there is a facility to do this on the site? Also, is there a real danger that replacing these files will require a system restore? Or is that chance minimal....

Cheers you lovely lovely people

A really simple question. What isnt working that makes you want to replace these?

tapiperf.dll belongs to Microsoft Windows Telephony Performance Monitor

autochk.exe is a part of the Microsoft Windows operating system. It allows functionality to revert core system settings back to their original state, and to backup where necessary. It is part of imagineLAN`s ConfigSafe.

thanks for your replies

rich, i would do a repair install but i upgraded from vista, and don't have a dvd for this. i suppose i could burn the iso to a disk... but will this have the repair install capability like a clean install win7 installation dvd would? either way, that upgrade file is on a portable hard drive far, far away..... no immediate use to me now.

zigzag, there is no critical reason. i just want to PREVENT later errors IF indeed these two corrupt files are deemed important enough to fix.. and that is part of what i'm asking in this forum - should i try and repair, or ignore?

carl, thanks for the info. i'm not advanced enough to know what level of importance these files hold, however.. I would be guessing if I tried to interpret your input. autochk sounds pretty important to my untrained ears, from what you just said!

Thanks, sounds like I should replace autochk at the very least then..
So what's the solution?

Alex, you can try to update it through Microsoft. You will probably have to do some searching of the various MS sites. You might try posting at this site to find the answer: Microsoft Answers Forums

I would not be overly concerned since you are not having any problems. Let us know if you find out how to fix that file.
