C and E can t be opened

I don't know how it can't be opened, whether it doesn't reflect anything when you click on the drive letter, if so, you can try to see if it can be opened in safe mode, if it still doesn't work, redo the system eight.

Reinstall it. That's it. There will be a lot of problems left. But get a brand new one.

Right-click on the workaround for denying access to the file "Open With".

Open Notepad.
