Windows 7: SFC /SCANNOW Command - System File Checker

4 Weeks Ago   #930

Dual boot - Win 7 Pro 64-bit and Win 10 Pro 64-bit
Point sfc /scannow at a downloaded .iso of Win 7 Pro 64-bit?

Brink - When I do a sfc /scannow (or similar) to touch up my existing Win 7 Pro 64-bit SP1, can I point it to a new download of the Win 7 Pro 64-bit SP1 installation .iso?

A MS tech is suggesting that I repair my existing Win 7 Pro 64-bit SP1 by doing an "inplace upgrade", and so I downloaded the .iso per his directions. But before actually running it from its setup.exe, is there a way to get its benefits without the risks, via sfc /scannow or similar? And would it be that iso or some "tech" equivalent download?

Hello glnz,

Let's see what your sfcdetails from OPTION THREE report to see if there's anything that actually needs to be repaired. Hopefully, it's something that's not needed or critical.

Brink - totally clean, both the scannow and the desktop .txt report.

Is it still possible there are any errors or corruptions of ntdll.dll or kernelbase.dll ?? Or are we confident there are none?

These two dll's appeared in two Event Viewer Error messages (as the relevant "modules") over the last month in connection with my problems UNinstalling and REinstalling Office 365 Home 64-bit.

Can we say 100% that they're OK, or not sure?

If SFC didn't report any issues with them, then they will not be corrupted or modified.

In this case, you have some other issue causing the error messages that should be continued in your other thread.
