About WIN 10 myself experience.
I have to confess. At the First i was surprising with the new OS Win 10 PRO x64. But after a while on working with softwares that require OpenGL algorithm i found big issues and a very unstable OS to have a nice workflow.
I found that the possible main reason for Win10 wont work properly is due the fact that all people u have GPU card from fabric for work under DIRECT X 10 and 11, the new OS 10 will replace that old DirectX properties with an image emulation for working under Windows 10. (i think this was Microsoft intent to push all users for their new OS)
So, all that GPU cards need to work under a not native software emulation that will causes buggy issues, specially under Rhino, CAD, SKetchup, Artlantis, PHOTOSHOP, ILLUSTRATOR, INDesign and so on. (mostly my work softwares).
I have experienced the same frustrations.
The very first was when i upgrade my Win7 to Win10 under the Microsoft automatic upgrade… Result in all messed up and unstable OS.
Second… i test a fresh and clean installation, from BIOS, of Win10… results in better performance, small gaps, and small issues. But in fact, all OpenGL softwares start to crash after an hour on work.
Third… I have to get back to what i found the best reliable and stable Windows OS - Windows 7 x64 -
I was able to get the work flow that i miss under Win10. I was able to work without bugs, crash or any kind of issues.
…What i try to mean is… Win 7, for now, still is the best Microsoft OS which show better stable performance… I think we only need to go forward if we buy new hardware components, specially prepared for new requirements, DIRECTX 12 and so on. And still wait for all new software stable versions which will work specially under Windows 10.
Windows 10 is to young for now. But i think it will be the one of the best Microsoft OS.
