As GDID is actually stored locally, in the registry, everyone can see their own, and the process doesn’t require any special credentials. All you need to do is run a simple PowerShell command, and you’ll see your own GDID.

Here’s the command:

$hex = (Get-ItemProperty 'HKCU:\SOFTWARE\Microsoft\IdentityCRL\ExtendedProperties').LID

"g:$([Convert]::ToUInt64($hex,16))"
