My mother being the fool that she is decided to upgrade her Windows 7 to Windows 10 without backing up her files. Consequently, she found upon restarting that all her photos were missing. However, they were found residing in an the Windows.old directory, and were then moved back to the Pictures folder. However, upon restarting the system once more, they were missing! So, she restored back to Windows 7 to find they were still missing. Have they been deleted permanently??
