Is it possible to demolish all the data at once (programs, and extensions with them ..), except for my OS (Windows 8.1), so that the OS remains clean?

Question

Windows

I would like to delete all data, leaving only my clean licensed Windows 8.1 OS?

Answer 1

My system disk size was 30gb, and usually it was free 0kb or ~ 150 mb, that is, I couldn’t watch the video or see the preview of the images. And I decided to take on this matter to the fullest and in the end I succeeded - I freed up as many as 12 GB from all the trashed space and could still, but these are quite enough, although I also really did not want to reinstall the axis.
I decided to describe detailed instructions and methods even in my first article. :o
