Desktop doesn't show when opened account

So my mom had problems with her computer (she couldn't print stuff or something like that) so she used the family computer anyway she used my account and I kinda don't like that. So I decided to make her a account anyway I made her a account and I was going to launch it for testing reasons or whatever and I was able to log in but when I did it was completely black. Well except for the mouse and McAfee notification saying I haven't paid yet for stuff on it (I have no Idea why I haven't deleted it I have malwarebytes) anyway thats all it shows I was able to log out using Ctrl Alt Delete I tried fully logging out (didn't work) I tried just saying change user (again didn't work) I tried a different user to see if it's the computer not the account and I was able to get in my account. Please tell me ways of fixing this problem. (I am using a windows 10 btw)
