Problem:

When desktop is deleted and user logs back in to the desktop the MS store apps which were installed by the user in previous session are missing.

Symptoms:

No custom user MS Store Apps are saved between non-persistent sessions.

Possible Resolution(s):

1) Verify that ProfileDisk is part of the ProfileUnity configuration. If no ProfieDisk in use

a) Create "Virtual Disk" Rule:

• Mount Location: Mount to Path
• Mount to Path: %localappdata%\Packages 
• Storage Type: Microsoft VHDX Image
• Virtual Disk Path: \\Server\Share\%username%\VHDs\packages.vhdx
• Size (GB): 10
• No Compression
• Type: Expandable

b) Create "ModernApps Classes" Portability Ruleset (Portability Management) to save following registry:

Registry Rules:

Merge Tree HKCU SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion
Merge Tree HKCU Software\Classes\ActivatableClasses\Package
Merge Tree HKCU Classes\Extensions\ContractId\Windows.Protocol\PackageId
Merge Tree HKCU Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore

c) Create Portability Rule (Portability Settings) to save and Restore the "ModernApps Classes" Ruleset

• Actions: Save, Restore
• Ruleset: ModernApps Classes"
• Apply Registry Rules
• Save Path: (your current portability save path)
• UID: ModernAppsClasses

Note: Persisting apps are not tested between different builds of windows. It assumes that the Windows 10 build does not change between logons. If it does the packages.vhdx might need to be deleted before logging in to a new build of windows 10. 

2) If there is an problem with initializing or loading the modern apps please follow instructions Below:
