Store app greyed out, doesn't start

I've all Telemetry related services disabled and store and other apps were working fine,
may be updates get stuck because of that ?? idk !


While searching for another fixes for my problem, I found this topic,
where one reply has nearly the same commands suggested by OldMike65.

Although I've used this code multiple times with no luck, I carried on and tried the rest of solution and used this code:

Code:

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

and voilà !!!! this time to my surprise Store is WORKING !!!!

Thank you guys very much for your help.

I'm curious to know how much space does an image take ??

And what exactly is included in it ? apps only or apps + data ? will my installed prog be there or I'll have to install all of them again if used this image ?

i had the same problem.
