I noticed that paint and notepad were not working. Notepad didn't launch at all, and paint said something like "unable to create file." I tried uninstalling and installing in the optional features, but it failed to reinstall. In addition, in windows is not updating, and, it always says "Download error "0x80070002". I did the sfc scan and it said it fixed corrupted files, but nothing changed. DISM /Online /Cleanup-Image /Restorehealth failed at around 70% and says source files were not found" It does the same thing when I set a wim file as the source. I downloaded the windows 10 iso installed it (to the same version 21H1), and it too gave an error and failed. It said "0x8007001f â 0x20006, The installation failed in the SAFE_OS phase with an error during REPLICATE_OC operation. The windows recovery environment (I'm not sure if this is what it is called) does not boot, and just shows a blue screen with an error message without even displaying the windows spash screen. Also, my restore points got deleted when I tried a tutorial on fixing DISM. The Tweaking windows repair app and chkdsk also failed to solve my problem.
How would I fix all this? I do not want to reinstall windows as I will have to reconfigure and install all of my apps and settings.
