Windows Account issues

[750XL]

Hello all, hoping someone can help me with this

• PC hasn't been turned on for over two weeks, was fine when it was switched off
• Turned PC on today, logged in to find my desktop was basically 'like new'
• Some programs (not all) are in my Start menu, but when opening them you have to set them up like you would on a new PC

My computer has two accounts, one for me (named Admin) and one for my girlfriend. The 'Admin' account I've always, when used now, is basically like using a new account having to set everything up from scratch etc. However, if I go into C:/users I see my 'old' folder with everything in it.

When I get to the log on screen, I'm faced with two accounts (Admin/Girlfriend).

However, when I go into User Profiles and then 'Configure advanced user profile properties' I see these accounts

Unknown Account / 10.4mb / Local
Default Profile / 1.50mb / Local
MyName / 105gb / Backup - I'm assuming this is my 'old' account, any idea why it's status is now 'backup' or how I get it back
Girlfriend / 913mb / Local
UpdatusUser / 10.4mb / Local

Any ideas what's going on

This may help:

User profile status set to backup - Microsoft Community

Otherwise this:

Fix a corrupted user profile - Microsoft Windows Help

I'd be concerned about a user profile size of 105GB, though. Try to move data to another folder or disk.

Since the PC was unused for some time, I'm also wondering about a dodgy BIOS battery?

Saab, I love you.

Followed the steps on the 'comments' section of the first link you posted. Took me a while to get my head around the registry edits but it worked.

Thanks!
