<human>: So I recently upgraded to Windows 10. I play a lot of games but mainly I play Witcher 3.
After a lot of googling and searching I couldn't find any way to open up any Windows 10 apps like store etc.
So I switched account to guest to check if its working there, yes, it does.
An idea struck my mind (worst one ever)
I made a new profile for myself and DELETED my old one COMPLETELY.
Only after a few minutes I realised what I had done. I fired up Witcher 3 and boom! All the saves were gone..(I know it's dumb)
My 50+ hrs of play time (lvl.25) vanished into thin air...
I am very much concerned about my games and  of course I panicked, because I did not have any back-up...Not even cloud or anything..
Started surfing again for ways to fix this fu I had done.
Well luckily I had a back up in portable HDD..Although it was lvl.9
Yep, I recovered my old saves, but they were all corrupted...

Give me the gist of the text in a nutshell
<bot>: Windows apps wont work, deleted that user and created new one, lost 50+hrs of witcher 3 playtime.
