You don't have to be a MS-hater to agree that windows is going downhill! Many of the features of Windows 10 are half-baked or a downright no-no for a professional OS.
- 'Settings' is not very good and requires going back to the old 'Control Panel' more often than not. I guess that's why it's under the context sensitive menu over 'Start' now?
- Theming is a joke compared to Windows 7.
- Passing on of information to MS (telemetry, search info, ...) without being able to turn it off is bad. The 'anniversary update' even removes some of these opt-out options from the group policy editor. I used a Pro version just for this reason, needless to say I deinstalled the anniversary update as soon as I found all this out.
- automatic updates is scary in a professional environment!
- Edge. Nuff said ...
- Network sharing is confusing as hell.
- Cortana. Right ...
- ...
The problem is fundamental with regards to the road Windows is taking, and makes it a questionable choice as a professional OS (I work in the medical sector!).
Regarding bugs, it is really annoying that some of the major problems keep rearing their ugly head and are not addressed even though they existed for a long time. At the top of my head I have:
- The file Explorer, which I see as a major tool for any OS is just bad. It's reaction to file system events just keep coming late, changing the UI seconds if not 10's of seconds after changes to the file system have actually happened. Also a problem in Windows 7.
- Icon placement is erratic, I need a special program just to keep my icons in place after any sleep or hibernation on a 2 screen setup. Woooow!
At home I upgraded to Windows 10 solely for gaming and getting DX12. At work we are nowhere near migrating (5000 PC's), and the question begs if we ever will if MS does not change its intentions fundamentally.
