SFC /scannow does not work - what to do??


Greetings.
After some troubble with my PC I wanted to restart in safe mode, but it can't do that. Breaks off and write something about a "hard crash", only the taskbar works, and I can also ust winkey+R and start regedit aso.

Because of this I wanted to run a "sfc /scannow", but that does not work either! It stops sometimes at 1% and sometimes at 2%.
So what do I then do to get my system on its feet again?
 

It's a known problem that sfc doesn't work, and has been this way since the first releases.

You can't run in safe mode either, as the start menu won't work in the current incarnation. This will get fixed eventually, but right now not much you can do. You probably just have to re-install.

Hi Burgurne!

If you have the ISO for 9926 burned to DVD, you can try this. Substitute your DVD drive letter for "G:".

----------------------------------------

Use ISO DVD from current build (i.e. 9926) for source (G


Run following at Admin CMD prompt:


DISM /Online /Cleanup-Image /RestoreHealth /WIM:G:sourcesInstall.wim:1 /LimitAccess


Run time ~ 15-20 mins




Log file in c:windowslogsdism

------------------------------------------

The full tutorial is here, bur this is the cmd line using a DVD.

DISM - Fixing Component Store Corruption in Windows 8

Hello Burgurne,

In addition, see if doing what's in the blue note box at the bottom of OPTION THREE below may help.

SFC Command - Run in Windows 10

I have now tried SFC /scannow again, and still a nogo.
I have attached the sfcdetails.txt to this post as requested in the blue box in Option 5.

Any clue of what is wrong?

See post 2. It doesn't work in 10 preview and never has.

There should be a new build this week - I'd install that.

Have you tried the DISM in my reply to you?

Updating the component store will not help if you can't run sfc /scannow as it is sfc that replaces the objects that are actually used

Oh! I didn't know that. So the DISM process actually repairs the winsxs/backup dir?

Yes. sfc replaces corrupt system files by copying them from the component store. If the file is missing or corrupt in the component store it will fail. You can fix the component store with dism (either over internet or using an image). Then if you run sfc again it should work.

That's why people suggest running sfc, dism, sfc.

The trouble with TP is sfc doesn't work (only because of its preview status presumably).
