what is windows shell experience and why do i get a window telling me to ask for permission to use it

Windows Shell Experience Host points to the process shellexperiencehost.exe in Task Manager. The purpose of "Shell Experience Host" is to provide Universal App integration in the Windows Shell (Windows Explorer), notably the taskbar. In simple, it responsible for the running of the Universal App in Windows 10. The file ShellExperienceHost.exe is located at %SystemRoot%\SystemApps\ShellExperienceHost_cw5n1h2txyewy.

If its popping up, try the following:

Open Start, type: CMD

Right click CMD

Click Run as administrator

Type in at the prompt OR Copy and Paste these one at a time : (Hit enter after each)

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /RestoreHealth

Also run the System File Checker utility:

Open Start, type: CMD

Right click CMD

Click Run as administrator

At the Command Prompt, type: sfc/scannow

This will check for any integrity violations

Restart your system

Didn't work and this is a fresh install of Windows done by Microsoft level 3 or 4 (So many upgrade transfers I lost count). They did it all themselves remotely to try to get rid of the issue but, it still persists. I am the one who handles Microsoft Family so the only adult I could ask is myself. There is also no way to add this program to allowed apps for adults.

Bump

Same issue.  Took the recommended steps.  All came out fine but did not fix the problem.

Same problem here, too:

Ask for permission

You'll need to ask an adult in your family if you can use:
