Tested with a logitech BT keyboard and the drivers for it are not included and WU won't offer them. I don't have other BT keyboards to test but other types of BT devices like mice and headphones are pairing without issues.
Open Shell will not run on Server 2025 at all, perhaps because it is an executable file without a digital signature? Is there a way to make it run and how? Sorry for panicking, it works after a Windows update and restart.
