Repair the Microsoft Store and Apps

This fixes problems with the Microsoft Store and Apps.

It also fixes these problems:

1. You cannot left click the SPEAKER icon and change the volume
2. You cannot left click the NETWORK icon and it bring up the list of available networks
3. You cannot add a new local user account.  It says "Search for app in the Store"

Here is the steps to fix it:

1. Launch Powershell as Administrator
2. Copy and Paste this command:    Set-ExecutionPolicy Unrestricted
3. Select YES TO ALL
4. When that command is done, copy and paste this command into Powershell:     Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
5. This command will take a while to run, so be patient.  And it will seem like its hung at several points.  WAIT FOR IT!!  You will know its done when you get back to the command prompt.
6. Restart the computer.
