I tell you what. We've done some pretty significant updates to our ICT environment in the time since I've been working for this department, including some updates to the OS. The project to update all Windows 7 and 8 computers to Windows 10 was not seamless, but it seems to me that it was a lot better than the current Windows 11 rollout.
We appear to be getting a remarkable number of (usually) very minor, very specific issues that are only affecting Windows 11 computers. Example: headset microphones plugged into regular audio jacks and the internal microphones of laptops return very quiet sound regardless of audio settings, while USB headset mics are normal. Also, if multiple monitors have different scaling settings, the Snip & Sketch tool just ******* doesn't work. This is consistent, and common, and predictable. And, apparently not something that UAT for the new OS picked up.
