I have connected 2 new PC's and 1 laptop to an exsisting AD.
When I log in with a non-admin domain account the store is not available as are the 'basic' windows 10 apps. (windowsdefender, calculator, etc)
I can see the Windows defender shield icon next to the clock but clicking it to open it gives the error message as seen in the subject.
Using the calculator shortcut on the keyboard gives the same message but with calculator instead of windowsdefender.
I found a couple of tips which did not solve the issue.
typing the following in an elevated powershell.
Add-AppxPackage -Register -DisableDevelopmentMode “C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml”
2. using the cortana workarround.
I managed to make the apps available on 1 of the devices by resetting/reinstalling windows.
It did not work on the other PC and also not on the laptop
When Logged in as local admin or domain admin the previously mentioned apps are all available and running properly.
