Is a reboot needed after the SFC has made corrections?

Are those examples from your own CBS logs?
Did SFC state that a reboot would be necessary?
I think Brink might be interested in the info so he can include suitable comments in the SFC tutorial.

That's because you tried to run its Cmd prompt command in a PS window.

I see. So I tried it in a command prompt and it just showed this repeated over and over, which wasn't helpful at all:

if there are errors in SFC the only way certain files can be repaired is by restarting the system
as some files needing repair may be in use by the system and only a restart would be able to have these files replaced.

then after the restart i normally re-run SFC again just to check
sometimes it can take several runs of SFC and restarts to fully repair a heavy damaged system.

best of luck Steve ..

Copilot's answer doesn't say to boot after repairs either. In its last sentence Copilot said:

Microsoft’s documentation doesn’t explicitly say “you must reboot,” but the mechanism itself implies it.

Nothing like

then? That's a shame.

I extract a list of repairs [only] using a modified form of the Cmd prompt command so I don't have to read through reams of boring entries.
After I've run it, I check the dates-time in the output file and delete the old lines if, as is normal, I am only interested in the SFC run I have just done.
%windir%\system32\cmd.exe /c "%windir%\system32\findstr.exe /c:"[SR] Repair" %windir%\Logs\CBS\CBS.log >"C:\%UserName%\Desktop\%ComputerName%-SFCResults-Repairs.Log""
If you have relocated your Desktop path then put that in in place of my C:\%UserName%\Desktop

And that Diskpart article I linked to stated that SFC would say if a reboot was necessary for that reason and illustrated such a response.

No, nothing except those 4 lines I quoted, repeated until the end of the file. Doesn't matter now anyway. I've noted these steps for the future if/when I run SFC again.

There are different types of sfc /scannow repairs.

Some require reboot and some don't.


On a regular basis this script:


Batch files for use in BSOD debugging - Windows 10 Help Forums

Information This thread is for use by the BSOD team to store batch files that can be used to collect additional data, fix settings or anything else that is useful in debugging BSOD problems in Windows 10. The way I see it working is the first
www.tenforums.com www.tenforums.com

is run in the BSOD forum room.

It starts with sfc /scannow. then scanhealth then restorehealth then repeats sfc /scannow.

Code: 
sfc /scannow
dism /online /cleanup-image /scanhealth
dism /online /cleanup-image /restorehealth
sfc /scannow
chkdsk /scan


These are not the exact reports but similar:

At times the first sfc /scannow reports corrections made and the second without corruption.

Other times the first sfc /scannow reports corrections made and the second reporting unable to run due to a pending repair/reboot
