Introduced first in Windows 8.1, Assigned Access is a setting that lets you restrict a specified standard user account to only use one Windows Store App when signed in. It’s also called Kiosk mode because you can restrict customers to only use one app on your PC. When someone use the Assigned Access account to sign in, they won’t be able to switch apps or close the app using any attached devices. All they can do is use that app in full screen mode.
How to set it up in Windows 10
1. Create a new standard user account.
If default universal apps are the only ones you will need to run in Kiosk mode, a local account is good enough. Otherwise, you need to go with a Microsoft account. You can’t Assign Access to a family account.
Go to Settings app → Accounts → Family & Other users, and click Add someone else to this PC in Other users section.
2. Sign in using the new created account.
The first-time sign-in will install all default universal apps. You can also install apps from Windows Store that you want to use in Kiosk mode later on.
3. Log off and switch back to the local admin account you used earlier to create the new account.
4. Open Settings app again if you haven’t closed, and go to Accounts, and Family & Other users. Scroll to the bottom and click Set up assigned access link. Choose an account that will have the Assigned Access, and pick an app that you want it to run.
5. Log in again using the Assigned Access account to test it.
That’s about it. To exit the account, simply press Ctl+Alt+Del and you are out.
