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?
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.
