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
