Go to “Settings -> Accounts -> Sign-in” options then scroll down to “Privacy” and switch the “Use my sign-in info…” slider to “Off”. If you’ve noticed a pattern of your Start Menu misbehaving each time you have a Windows Update, or simply when you restart your PC, then a couple of people have suggested that this could be the solution. Reboot your PC, and your Start menu should be up and running again. To run the Application Identity Service, press Win + R, type services.msc into the box, then in the Services windows right-click Application Identity and click Start. For the most part you don’t need to touch this, as it generally knows what’s right for your PC, but forcing it to run when you’re experiencing the Start menu problem can help fix them. The Application Identity Service in Windows 10 uses a service called Applocker to decide which applications are and aren’t allowed to run on your PC.
