Windows 10: I am seeing my daughters stuff and she is geting my pics and stuff on her computer why???

My daughter used my computer for homework. Now she gets all my pictures, files, and everything. the sync accounts thing is shut off. It still shows me as the administrator so why is it that when she changes her screen saver it changes mine, when she renames her name it changes mine also. This is messing with all of our computers because now her computer is full of my data and vice versa. I have tried to stop it but your help community is so far NO HELP AT ALL why is Microsoft not helping us or why doesn't it have a lock button so others can use the computer without snatching or syncing peoples data and accounts without permission from the ADMINISTRATOR OF THAT COMPUTER ?????????????

Shortcut key for "My Stuff" ?

Using Windows 10, here's the steps I'm taking to search for files on the computer:

• Click Start Menu (or tap the Windows key on the keyboard)
• Start typing a search term
• Click "My Stuff"
• When it finds your file, click it to make the file open
• If you want to open File Explorer and peruse similar files without opening files:
  • After clicking "My Stuff" (in Step 3) go to the bottom area under "Other places to look" and click "File Explorer"
  • File Explorer opens
  
  Question: I don't want to use the mouse to click "My Stuff" in step 3. Is there a shortcut key?
