I've been trying to upgrade from Windows 8.1 to Windows 10 and the following error message pops up:
Windows 10 couldn't be installed- error code: 80070652
I tried installing Windows 10 a year ago (just after the first release) but my laptop was running so slow I went back to Windows 8.1 a week later. Not sure, if that has anything to do with that..
I would be extremely grateful for help!
