Windows 10 control panel printer not showing

In File Explorer right click on “This PC”
Click on “Manage”
The “Computer Management” window will open
Click on “Services and Applications” and then click on “Services”
When the list of services opens scroll down to “Device Association Service” and check its Startup Type. It should be Automatic (Trigger Start). If not right click on it and open Properties. Change the Startup Type to Automatic.
Then scroll down to “Device Install Service” and check its Startup Type. It should be Manual (Trigger Start). If not right click on it and open Properties. Change the Startup Type to Manual.
Then scroll down to “Device Management Enrollment Service” and check its Startup Type. It should be Manual. If not right click on it and open Properties. Change the Startup Type to Manual.
Then scroll down to “Device Setup Manager” and check its Startup Type. It should be Manual (Trigger Start). If not right click on it and open Properties. Change the Startup Type to Manual.
Once the four services are set as in steps 5, 6, 7 & 8, reboot the computer.
After rebooting check the “Devices & Printers” section in the settings. The missing printer should now show as it should.

Repair 10 start menu and notification center

powershell

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml” -Verbose}

The Applications event log is full of ESENT errors about a TileRepository being damaged and it can’t repair it, so I took backup and then deleted all files in C:\users\{username}\appdata\local\TileDataLayer\Database. Reboot and everything works fine again BUT you will lose your customisations and will be left with a blank start menu.

 

Other command: PowerShell -ExecutionPolicy Unrestricted -Command “& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + ‘\AppxManifest.xml’ ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}”
