Windows 10 - Start menu and apps not working

From time to time, for some reason, the Windows 10 start menu doesn't work, and apps don't launch. Weird as it is, it can be fixed by running a PowerShell command:

1. Right-click the task bar and select Task Management;
2. Select File > Execute New Task;
3. Type in "PowerShell", select the Administrator option and click OK;
4. When PowerShell is ready, enter the following command and press enter: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
5. Restart the PC;

The command takes a while to execute, and may yield some errors, but after the reboot my start menu and apps work again.
