I use Windows 10, version 2004 and build 19041.450
And now why I need to use DISM? So the problem is that when I run Windows update, it downloads, and isntalls, but then it shows error 0x800703f1. So I asked in the other conversation here on MS answers, what should I do now. They recomended me to rename the softwave distribution folder. It was unsuccesfull because it said: A duplicate file name exists, or the file cannot be found. And: Access denied.
So then I tried to update PC with media creation tool. Unsuccesfully, because after 1,5 hour it wrote: changes made on this computer will be canceled.
So I tried to uninstall Avast antivirus and then this command: DISM.exe /Online /Cleanup-image /Restorehealth. And it wrote me: The configuration registry database is corrupt. (error 1009)
So I absolutely don´t know what to do now, and I would be glad if you try to help me.
