Thanks for the feedback. We'll find another way to reference the GUID as it changes with each release and this updated one is now already out of date. We'll keep this open until we make the changes to keep you updated.

Hi @dknappettmsft,

Can this PR be closed or are the above-mentioned changes still in progress?

[dknappettmsft]

Hi @Court72 - still in progress due to other priorities and settling on a method to deal with this. Apologies that it's taking a while.

This article has been updated to use a different method for detection and uninstall that doesn't rely on the product code.
