That is wonderful news & coming just as my head was nearly empty.
Well - make a Windows system image now, at "START, Settings, Update & Security, Backup, Go to Backup & Restore (Win 7)", in case the problem recurs or the next problem is even worse. Make the Repair Disc to restore it with, or ask Cortana for "Recovery Drive" to make it on USB. Also, see...

Restore a System Image Backup in Windows 7, 8, 8.1 and 10
Note: That is a 3rd-party site. Sounds good, but I know nothing of any link or download there.
Or at least ask Cortana for "Restore", & make a restore point. But eventually it will get old.
Good luck, & keep us informed.
