Photos App missing under certain user accounts

My computer is joined to a on-prem domain running Windows 10 Enterprise x64, build 1709.
My user profile is roaming with Folder Redirection enabled (by Group Policy).

I had to recreate my roaming profile and ever since then have been having issues. First, the built-in Calculator app had disappeared. I managed to get it back by running the following PowerShell:

Code:

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

2 weeks later I noticed my default photo viewer had been reset. I tried to change the file type association of .PNG files, for example, to Photos but couldn't find it. If I switch user and log in as the local admin, I see the Photos app.

I've tried various PowerShell commands in an attempt to get the Photos app back but am failing. Here are the commands I've tried:

Code:

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

Code:

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

Does anyone know how I can get it back? I'm also wondering what else I've lost. I still need to find why this occurs when I delete my cached roaming profile.

I found the fix. In addition to deleting the cached user profile, there is a registry key you need to delete under:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore

We did not have to do this on Windows 7 so it means we will need to remember to perform an additional step on Windows 10. I hope this helps somebody else. Here are the steps:

1. Log the user off
2. Log in as the local administrator
3. Open Registry and navigate through to

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

4. Take note of the user SID (e.g. "S-1-5-21-3240762094-2299924057-4138702961-2710")
5. Delete the user's cached Windows profile
6. Delete the key matching the user SID in 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore', e.g.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\S-1-5-21-3240762094-2299924057-4138702961-2710
7. Log the user back in again to re-download their cached profile
