Windows 10: sister logged on to my laptop using her outlook email account

my sister logged on to my laptop using her outlook email account and now she is listed as the admin and all my files are under her account how can I change her from admin and get her out of my account but still let her use my laptop and not lose any info?

:)

 

Wrong account linked to computer

My little sister tried to set up a Microsoft store account and the email she used is not one she can access. Windows now prompts her to log in to her computer with that same account. Since it is not her email she has no way of logging in.

 

How do I remove a laptop from my account

Ask your sister to set up a new account on the laptop in her own name
as an Administrator and elect to sign in with a Microsoft account. If she doesn't already have an account she can create on using her existing email address or create a new one along the lines of *** Email address is removed for privacy *** or *** Email address is removed for privacy *** - been while since I've done
it so I'm not sure which will one will be offered/created for her.

Log out and then log back in with her new account and, once logged in using her own profile, she can delete your account for the laptop assuming there's no data you want.... ?

Cheers

 

Microsoft make it (too) easy to accidentally switch from a local account to a Microsoft account, though usually it's your own account that gets switched to. This Tutorial tells you how to switch back.

Once you've switched back your sister won't have a log in on your PC. If you want to let your sister log in in the future, you could create a second account for her. You can even set it up as a Microsoft account. You could also make sure it's a standard account, not an admin. There's a Tutorial for that too.

How I have done it on mine is
log out switch user and whoever wants to can use that account
