      @fck.rt: I suggest to download Windows 8.1 and perform a fresh Windows installation.

    I tried all the listed solutions from solution number 1 for days but I still encountered errors especially Code 80073712 and Code 8024A000 (both for my desktop and laptop). At first I wanted to update while keeping my license but it drained all the neurons in me since they didnt work out. But yey, the only thing that worked is the solution number 2! Thank you for this!
