While waiting... What can corrupt the user profile?

Its not always clear, but issues within Windows Code, Data corruption, registry corruption, other software interfering.

But as windows never shares the source code on how this works, it is never clear.

It's my wife's machine and she has an admin account named Cecilia and a password XXXXX

ok, then we call this new account Cecilia1 with password XXXXX

Turn off the computer

Turn it on and keep tapping F8 until you get to the menu

Choose Safe Mode with Command Prompt.

When you are able to type, type in the following commands.

net user /add Cecilia1 cecilia1

Press enter, then type in

net localgroup administrators Cecilia1 /add

Press enter

Once done, the new user account is created and placed in the Administrator Group.

Then restart the computer and log in with this new account. You will have to use this account from now on, but if you need to access and copy the files from the old account, click Start, Computer.

Go to c:\user and click on the folder from the old user account, and all the files will then be accessible.

If you have any difficulties at all, please do not hesitate to let me know so I can assist you further
