Windows 7: Anyone Familiar with sfc /scannow?

Anyone Familiar with sfc /scannow?

Hi all

I'm having trouble resolving this issue in Windows 7 that may (or may not) be causing my system to freeze up.

When I run a scannow in an elevated prompt a get errors, so I get a Notepad log showing me what's what.

The log appears to indicate that the problem is with explorer.exe


CSI 000003a3 [SR] Could not reproject corrupted file [ml:520{260},l:28{14}]"\??\C:\Windows"\[l:24{12}]"explorer.exe"; source file in store is also corrupted

End quote.

So I slipstreamed Windows 7 with SP1, used 7-Zip to go into the correct set of files (W7 Premium) and replaced my explorer.exe and the shell32.dll file.

However, scannow still shows errors. I feel I may have read the data (above) wrong.

If there is anybody who can shed some light, without suggesting a clean install, I'd really appreciate it.

I have done a manual restore point just in case.

Hello Bes,

You might see if downloading and running the 64-bit (x64) System Update Readiness Tool for your installed 64-bit Windows 7 to repair the component store (source), restart the PC afterwards, and try the sfc /scannow command again may help.

SFC /SCANNOW Command - System File Checker

Hope this helps,
