I think this needs to be discussed more. I'm waiting for Vladimir to
join us.

You can research if it's possible to use MSI Product ID GUID for PSDK to
get the path. The ID won't be changed because Microsoft don't recommend
it. I think they follow their own recommendations.

But there are also an easier way. You just forgot to search HKCR. The
key is there. Don't be afraid - PSDK is installed by MSI and the key is
restored each time a new user logs in. So all users have the same key.
Even the users which were created after the installation of PSDK.

I'm going to review it tomorrow.
