This post shows students and new users steps to change or modify a kiosk app in Windows 11 when using kiosk mode. We recently showed you how to set up a kiosk system with Windows 11.
Windows allows users to assign access and restrict people to using only one app, so their Windows device acts like a kiosk. When the kiosk account signs in, the app is launched automatically, the person using the kiosk cannot do anything on the device outside of the kiosk app.
Because you can only assign one app at a time, changing the assigned app requires that you go to the Windows Settings app and change it there. You can change the kiosk app anytime you like.
If you haven’t already set up a kiosk with Windows 11, read the post below to learn how to do it:

Alternatively, you can use the search box on the taskbar and search for Settings. Then select to open it.
Windows Settings pane should look similar to the image below. Click Accounts> Family & other users tile in Windows Settings to expand it.
