It was rather simple actually. I've researched this and all you have to do is to go to your start-menu and search "Powershell". Right click it and run it as an administrator.
The next step is to copy this code and paste it in the Powershell, let it do it's thing. Basically this re-registers all of your modern applications and fixes any issues causing them to not work.
Here is the code :)
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Make sure you include nothing else but this code. I hope this helps you guys.
Cheers!
Thanks. But it gives me this error: Add-AppxPackage : Deployment failed with HRESULT: 0x80073D02..
I have tried the services fix too but can't enable the two last services..
