Windows 10: how to run sfc with offlogfile flag

Ran SFC , Got the following.

"C:\WINDOWS\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag."

Background is that the tablet's wifi and bluetooth aren't working, That means I can't run DISM or repair online.

I have an identical tablet with the same drivers. That is working no problem. I have also uninstalled the drivers and restarted to reinstall them. Also done a reinstall of 1809. sfc is still showing corrupt files. Problem came from failed 1903 update and rollback to 1809.

I am trying to see if the sfc logfile will help me repair.

I have already tried sfc /scannow /offlogfile=c;\scanlog.txt
and sfc /offlogfile=c:\scanlog.txt

:)

 

Sfc /offlogfile

I dont think the /scannow flag is compatible with the /offlogfile one...

 

Sfc /offlogfile


If I execute the command: sfc
... then I get the help, including the parameter /OFFLOGFILE

If I execute the command: sfc /scannow /offlogfile=E:\temp\scannnow.txt
... then the help is displayed, but no error message. What's going on?

I'm trying to run sfc /verifyonly and to direct the output to a file.
So I tried: sfc /verifyonly > E:\temp\verifyonly.txt
... and of course that worked.
But the text in the file is curious. Every character is taking 2 bytes, the first being x'00'

It's simple enough to write a script to get around these minor issues; I'm just curious why I should have to!

 

Sfc /offlogfile

I got /OFFLOGFILE from running the command SFC on my Windows 10 PRO Version 1809 build 17763.55
