This is a fine time to check if your backups restore and if not, start planning a new backup and restore.
If you are relying on a cloud system, then I have bad news.
I am using windows 10 and my windows live 2011 and windows 7 all just suddenly disappeared from my computer along with my saved bookmarks. Icons have disappeared and there is nothing showing on task bars. Nothing showing as to their existence anywhere. Help needed.........beejay29
