Hello! Hopefully someone can help me.
I have a Surface Pro 2 which I upgraded to Windows 10 on release day then rolled back a few days later.
Since then I have been unable to change any user account pictures or lock screens. For the account picture I get the message 'Account Picture Error - Setting the account picture failed, please try again'. If I try to change the lock screen I just get the waiting animation but nothing happens.
Thanks in advance for any help!
