I hoe i am not rude but please it is not windows apps folder. Wondows apps was just thecontext and why i followed the tutorial . The affected folder are obviously :
-programfiles
-windows
-program files x86
-users
I actuallyhave an image of whaat i selected with the windows repair app by tweaking. If you want to know what i selected and caussd my those issues please tell me

All 4 of those need to have their permissions restored, but \Windows is the big / main one - hard to boot when it doesn't have permission to access the boot stuff.

Make sure you’re not tired when implementing the fixes given to you. Care should be taken.

Reset default ACLs for C:\Program Files\WindowsApps

I just found this in my familly computer (not the one that has the issues) the version ks windows 10 , 22h2 , build 19045.3324 (the same as my computer)
The permissions for C:\Windows are similar to the one that i found in the windows 7 solution
The attached file is the familly computer not my computer.

I don't think it's you. I dropped out a while back, when it looked like @johnlgalt and @dracone and others had it covered. Maybe they're all busy or didn't notice that you had more questions. Anyhow, I feel like I would have to break a machine similarly and see if I could fix it via USB boot media before I could provide specific guidance, but it does seem reasonable that using takeown and cacls to reset the permissions has a chance. If no one else jumps back in, I'll see if I can run some tests.

ghali12345 · Nov 17, 2023

Oh alright , but i will just try the windows 7 tutorial because literally the family computer is the same version as my computer (19045.3324)
After i checked , icacls in the familly computer i found the permissions were similar to the permissions in the old post

I dropped out as well as I didn't want any possibility of conflicting information once @dacrone started assisting.

The problem that you can run into here is that while the permissions for the main folders are those, folders inside may be set slightly differently, depending upon the app, because the apps that run also need permissions to, well, run.

It's possible that will fix your issue(s) entirely - it's also possible that it will only partially fix them and new issues will crop up.

As you were working with Dacrone, I dropped back and watched, but my intent would have been to tell you to bite the bullet and cleanly reinstall Windows, as that way everything will be fresh, and no leftover / remnants of the ill-fated permissions changes going down the road.

i was waiting for you to run those commands from the recovery screen cmd

I would spend the money on a USB SSD, boot from your USB flash drive, and use Explorer++ or FastCopy to copy any data you need to the SSD. Then do a clean Windows install and reinstall your apps.
