Windows 10: Windows store wont open, and a load of apps are greyed out

Hey guys, I REALLY need help here. For some reason a load of my apps are greyed out, and windows defender and Windows store wont open. I've tried Powershell and that WSReset.exe thing, but neither seemed to have any effect. I'm at my wits end here and I really need to get this sorted. Any help would be deeply appreciated.

I have MalwareBytes Premium because my Windows Defender doesn't open or turn on if that's relevant. Please help if you know anything that might work

Windows 10 App store wont load!

Hi,

I suggest that you reset the Windows Store cache as per the below mentioned steps and check:

• 
  Press Windows key
  and R key together to open the Run Window.
  
• 
  Type wsreset.exe
  and press Enter key for the command to execute.
  

If the issue persist, I would suggest you to re-register Windows Store App and check. Please follow the steps:

a. Press Windows key + X.

b. Click command prompt (Run as administrator). type the following command:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.XML

Let us know if the issue is resolved or if you require further assistance.

 

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

 

photo app in windows 10 wont load

my photo app wont open, and I cant uninstall it for it does not come up in the apps list in the settings. But it is in the all apps list.

When I have tried to reinstall it from playstore it says already installed. But wont open, and the new Twinui default photo view app wont open any jpeg files it say "class not registered".

I have followed other suggestions of troubleshooting, and system scan with no results.

Any suggestions?
