Deactivated old VM Windows 10 pro for Intel license in subscription management. Created new VM Windows 11 pro ARM with Parallels 18 on new MBP Apple M2 silicon, macOS Sonoma 14.1. Updated to Parallels 19. Tried to activate conforming https://kb.parallels.com/en/114051 Windows 11 pro ARM. Activating with existing license applies in my case. Reactivate Windows 10 Pro. Result = Windows cannot be activated. What is the reason that the practice works differently than in https://kb.parallels.com/en/114051 ??
