I'm not quite following you. I am not upgrading or anything, I do have this Windows 10 already. I have been using it for quite a while now and this error came-up. I missed all your responses since I haven't checked my email til earlier because I did the Windows 10 refresh or reset.
In place upgrade = installing windows over itself, to fix any corrupt file and most system settings system settings. You said "reinstalling the apps was an hassle" so I assumed you did a fresh install. That's all
Sadly yes. I used the built-in reset in Windows 10. Do you have any guide in this "In place upgrade" in windows 10 by any chance?
Yes. Click on the ISO to mount it, click on setup.exe, when asked choose to keep everything. End of the guide
or dload mediacreationtool from ms win 10 site and run that (i do recommend run win repair tool from tweaking.com portable with defaults but in safemode with net).. next is easy stuff.
