I too, am looking for a good answer to this dilemma....
I literally have THOUSANDS of WIN10 machines in 300+ auto franchises running diagnostic & programming software from the manufacturer. Every week, I have another shop foreman calling and screaming that their software won't work and we spend hours rolling the systems back to Win10.
I don't WANT to block WIN10 updates! I cannot afford to...the software for diagnostics & programming rely heavily on .NET, and I WANT Windows 10 to update regularly.
I just don't want WIN11 to be available until they release the diagnostics & programming software FOR Win11.
It's infuriating that they will only let you "pause" the Win11 update for a period of time, and not give us the choice of suspending indefinitely until WE choose to allow it.
