I might downgrade this weekend and surprisingly Microsoft makes it just a couple clicks to do this for the first month (i did it for one computer that had compatibility issues). The operating system itself is really nice and fixes terrible windows 8 for the most part. The fact that metro apps run in a window instead of full screen is great. This makes windows development across desktop, phone, and tablet so easy.
But, the policies around the operating system is terrible really. But, I do know that Microsoft is planning to get away from big releases like 7, 8, 10 etc. Instead small releases like Apple, so being forced to update in the future is likely. Also, Windows 7 is already out of mainstream support and only has extended support. This means new features such as direct x 12 will never hit the platform...boo.
