Resolving issues with Store in Windows 10

UPDATE: If you found this page helpful, please retweet it

After upgrading my Windows 8.1 to Windows 10 I started having issues with Metro apps and the Store. It was simply not working.

When trying to launch the Store app I was getting: "This app can't open. There's a problem with Store. Refreshing your PC might help fix it.".

Possible solution #1

Right-click the start button, select "Command prompt (Admin)" and type wsreset.exe. Didn't work for me, I was getting: "You'll need a new app to open this ms-windows-store".

Possible solution #2

Right-click the start button, select "Command prompt (Admin)" and type powershell. Then type:

Set-ExecutionPolicy Unrestricted

And then

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

Didn't work for me either. I got this:

Cannot find path 'C:\WINDOWS\WinStore\AppxManifest.XML' because it does not exist.

I simply had no "WinStore" folder in my "C:\Windows"

Possible solution #3

Right-click the start button, select "Command prompt (Admin)" and type powershell. Then type:

Set-ExecutionPolicy Unrestricted

And then

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

Finally, it worked.

If none of the above solutions works for you - create a new administrator user and repeat the steps under the new account. You will have to transfer all the existing data to the new user profile from the old one.

UPDATE Thanks to Matthew in the comments. Many people are complaining about this error: + FullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand. This link link seem to resolve this problem.
