totally forgot about this regkey... In the past I actually wrote a script to dynamically correct this value, have a look:
#Requires -Version 5.0
#QueryDosDevice code from https://sourceforge.net/projects/morgansource/files/Powershell/SystemInfo/
#Build System Assembly in order to call Kernel32:QueryDosDevice.
$DynAssembly = New-Object System.Reflection.AssemblyName('SysUtils')
$AssemblyBuilder = [AppDomain]::CurrentDomain.DefineDynamicAssembly($DynAssembly, [Reflection.Emit.AssemblyBuilderAccess]::Run)
$ModuleBuilder = $AssemblyBuilder.DefineDynamicModule('SysUtils', $False)
#Define [Kernel32]::QueryDosDevice method
$TypeBuilder = $ModuleBuilder.DefineType('Kernel32', 'Public, Class')
$PInvokeMethod = $TypeBuilder.DefinePInvokeMethod('QueryDosDevice', 'kernel32.dll', ([Reflection.MethodAttributes]::Public -bor [Reflection.MethodAttributes]::Static), [Reflection.CallingConventions]::Standard, [UInt32], [Type[]]@([String], [Text.StringBuilder], [UInt32]), [Runtime.InteropServices.CallingConvention]::Winapi, [Runtime.InteropServices.CharSet]::Auto)
$DllImportConstructor = [Runtime.InteropServices.DllImportAttribute].GetConstructor(@([String]))
$SetLastError = [Runtime.InteropServices.DllImportAttribute].GetField('SetLastError')
$SetLastErrorCustomAttribute = New-Object Reflection.Emit.CustomAttributeBuilder($DllImportConstructor, @('kernel32.dll'), [Reflection.FieldInfo[]]@($SetLastError), @($true))
$PInvokeMethod.SetCustomAttribute($SetLastErrorCustomAttribute)
$Kernel32 = $TypeBuilder.CreateType()
$Max = 65536
$StringBuilder = New-Object System.Text.StringBuilder($Max)
#Get PackageInstallationRoot -> Drive
$PackageInstallationRoot = [Environment]::ExpandEnvironmentVariables( $(Get-AppvClientConfiguration -Name PackageInstallationRoot | Select-Object -ExpandProperty Value) )
$Drive = (Get-Item -Path $PackageInstallationRoot).PSDrive.Name
#Get HarddiskVolume from drive where AppV packages are currently installed
$AppVHDVolume = $Null
$AppVHDVolume = Get-WmiObject Win32_Volume | Where-Object { $_.DriveLetter } | ForEach-Object {
$ReturnLength = $Kernel32::QueryDosDevice($_.DriveLetter, $StringBuilder, $Max)
if ($ReturnLength)
{
$DriveMapping = @{
DriveLetter = $_.DriveLetter
DevicePath = $StringBuilder.ToString()
}
New-Object PSObject -Property $DriveMapping
}
} | Where-Object {$_.DriveLetter -eq "$($Drive):" } | Select-Object -ExpandProperty DevicePath
$AppVHDVolume = ($AppVHDVolume -split '\\')[-1]
#Find incorrect HarddiskVolume for each package and change to correct value
$matches = $Null
if($AppVHDVolume)
{
Get-ChildItem -Path 'HKLM:\SOFTWARE\Microsoft\AppV\MAV\Configuration\Packages' | ForEach-Object{

$CurrentValue = $matches.Values
if($CurrentValue -ne $AppVHDVolume)
{
Set-ItemProperty -Path $_.PSpath -Name 'PackageRoot' -Value $($(Get-ItemPropertyValue $_.PSpath -Name 'PackageRoot') -replace $CurrentValue, $AppVHDVolume) -Force | Out-Null
}
}
}
