BOOT

Running sihost.exe is a way to 'reboot' the shell. Might be worth a try.

Are you using local user profiles?

You could customise the default layout: C:\Users\Default\AppData\Local\Microsoft\Windows\Shell\DefaultLayouts.xml in the OS image, or clear the registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache on login.

Essentially, removing the Microsoft.MicrosoftSolitaireCollection app breaks dependencies for the vast majority of apps.

Did you remove the Microsoft.MicrosoftSolitaireCollection app?

Had this issue in v1803. Nice to finally know the cause.

I've not tried a network share, only using a local .png image.

Via a GPO that adds an entry in: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components] and removes the entry in: [HKEY_CURRENT_USER\Software\Microsoft\Active Setup\Installed Components]

This is what I'm using: https://github.com/SN29856L/RegAllAppX

Have you tried this fix?: Set the registry key in [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Spartan] RAC_LaunchFlags REG_DWORD value to 1

I use this in a startup PowerShell script: icacls "C:\ProgramData\Microsoft\Windows\SystemData" /setowner "BUILTIN\Administrators" /T /C icacls "C:\ProgramData\Microsoft\Windows\SystemData" /inheritance:e /T /C icacls "C:\ProgramData\Microsoft\Windows\SystemData" /inheritance:d /C icacls "C:\ProgramData\Microsoft\Windows\SystemData" /setowner "BUILTIN\Administrators" /T /C icacls "C:\ProgramData\Microsoft\Windows\SystemData" /grant:r Administrators':'"(CI)(OI)(F)" /T /C icacls "C:\ProgramData\Microsoft\Windows\SystemData" /grant SYSTEM':'"(CI)(OI)(F)" /T /C Remove-Item -Path "C:\ProgramData\Microsoft\Windows\SystemData\S-1-5-18\ReadOnly\LockScreen_P\*" -Force Allows me to customise the image to add announcements, etc.

Yes. If the filename doesn't change, it won't update the cached copy.

I had the same issue with any apps, even the start menu. Registering the Microsoft.UI.Xaml app on logon helped most of the time. Currently using a tool that registers all provisioned apps at logon.

What type of user profiles are you using?

I get the same thing when users are over their storage quota. (Because of redirected AppData folder).

The shortcuts get copied into the users profile. Setting file permissions allows per shortcut availability.

Tilt your head sideways and look again...

Try copying the shortcuts to: [C:\ProgramData\Microsoft\Windows\Start Menu\Programs\]

Another free timeslot = another cookery show.

Apply a custom start layout xml to specify the tiles.

I've never had a layout xml containing DesktopApplicationLinkPath work in any version post 1607. I use DesktopApplicationID instead.

You could try reinstalling the RM Serialization Helper.msi in: C:\ProgramData\RM\Connect\RMCoreUpgrade\CC4 Components\RM Serialization Helper

This is what I use to clear a failed core upgrade... REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Core Logoff" /f REG DELETE "HKLM\SOFTWARE\Wow6432Node\RM\PackageInitialisation" /v "Core Logoff" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "BlockLogon" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Package Title" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Package Status" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "CmdExecPause" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "RollBackIA" /f REG DELETE "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Bootstrapper Description" /f REG ADD "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Bootstrapper Heartbeat" /t "REG_DWORD" /d 0 /f REG ADD "HKLM\SOFTWARE\RM\PackageInitialisation" /v "Bootstrapper Status" /t "REG_DWORD" /d 3 /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "BlockLogon" /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "Package Title" /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "Package Status" /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "CmdExecPause" /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "RollBackIA" /f REG DELETE "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "Bootstrapper Description" /f REG ADD "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "Bootstrapper Heartbeat" /t "REG_DWORD" /d 0 /f REG ADD "HKLM\SOFTWARE\WOW6432Node\RM\PackageInitialisation" /v "Bootstrapper Status" /t "REG_DWORD" /d 3 /f

Try adding 'Domain Computers' to the GPO Permissions?

Tile data is stored either in the registry or a CloudStore.dat file.. or both. Depends on whether you're using local or roaming profiles.Updating the layout XML file or giving it a new last-modified date usually resets the broken tiles.
