Hello,
I noticed that I had corrupted system files that scannow could not repair. I tried Dsim without success. So I reset W10, losing my utilities. A lot of time to set everything back to how it was...
2 questions:
1- What is the difference between scannow from sfc and dsim? To me, they do the same thing, with maybe an advantage for Dsim to repair certain files reported as corrupted by scannow???
2- If I had, before the system reset, backed up the folders of my utilities "Programs" and "Programs (x86)" to a drive other than C:, could I have restored them to drive C: (yes) but would they have been usable?
Lastly, a bit of info for chatting among friends.
With my Windows 10 Pro, 2 out of 3 times the installations of utilities (like Adobe Reader for example) from launching the setup.exe installation found with Firefox fail: "This application cannot run on your PC, etc."
I found the solution: I download the setup files with Edge and I have 2 options offered: either install (which I choose) or save. No problem with the "install" option. Firefox does not offer the "install" option.
Can someone explain this to me?
Thanks and see you later!
Configuration: Windows 10

Hello,
SFC checks Windows system files when they are corrupted or modified.
It can repair them by attempting to replace them if a copy is available.

Finally, DISM allows three things:- to check and manipulate Windows images (WIM file).
- to install or remove Windows updates
- to check Windows store components (WinSxS folder).
DISM is limited on Windows 7; for example, it does not allow checking and correcting store components.
See these pages:
Repair system files with DISM
Finally, it can also mount and modify WIM files used in Windows ISOs.
This allows for customizing Windows ISOs.
For this last case, see this link:
Repair, mount Windows images
