how to run sfc with offlogfile flag

/offlogfile is for when you run sfc /scannow in offline mode, ie from say a winpe, win re, recovery drive or install media usb...

SFC /scannow /offbootdir=C:\ /offwindir=C:\windows /offlogfile:C:\scanlog.txt

this assumes that C: is your system drive ...sometimes the drive letter will change so use:

wmic logicaldisk get deviceid, volumename, description to list your volume drive letters to select the correct drive letter

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

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

Peter,

Before you go any further [since this whole thing might be irrelevant to your WiFi-BT problems], extract a list of what SFC cannot repair using this command

[it does not need to be run in an elevated command window, any old command window will do]
insert your own choice of path for the output file
Code:

Then look at SFCResults-Unrepairables.Log. Is it the same as this picture? All Windows defender ... hash mismatches?


Taken from my consolidated ditty on SFC errors [WD update problem] - TenForums

If it is the same list then you can dismiss SFC as having any bearing on your WiFi-BT problem. You don't even need to bother reading the rest of that thread. You can just return to fault-finding your hardware without the distraction of thinking SFC will help you.
