This does not work as my computers do not have HKCU\Software\Policies\Microsoft\Windows. I copied and pasted it into the find feature in regedit.
Chat and AI are annoying and waste my time, make a simple way to turn it off that actually works. Every time you update AI/Chat it is worse. SET IT UP SO I CAN TURN IT OFF EASILY AND HAVE IT STAY OFF UNTIL I MANUALLY TURN IT ON which will be never.
