Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I guess Rohn007 and others are no longer interested in this thread. Anyway, I'm documenting all this for my own reference. Today I opened a Powerpoint document that I downloaded from my email and sure enough another subkey was added to TargetedMessagingService in HKCU. And when I opened the document I got the message:
The new subkey skipped "2:en" and went to "3:en". So I did a rinse and repeat on that subkey: changed TimeToNextcall in Header to year 2025 and changed MessageScenario value in Body to 0.
