They've had a long history of building or other users compiling versions for Windows - https://www.gimp.org/downloads/ - has Windows and Mac OSX as options, as well as Linux.

On Windows, a better application that sits between MS Paint and GIMP in terms of features, extensibility and power is the free Paint.NET. [1]
On more than one Windows 10 machine, I have no problems running Gimp 2.8 build for Windows supplied straight from https://www.gimp.org/downloads/ It also works well on Windows 7. I can only assume that means it will probably work OK on the versions between 7 and 10.
I've experienced weird behavior with GIMP on Windows. It mangled my clipboard usage with Teamviewer (wth?), tablet support is hit and miss, and other just plain odd behavior.
That's not a complaint, I've no right to complain as I've not documented and raised the bugs.[1] I've just worked around them, which I appreciate is selfish.
But it works just as well/badly on 7, 8.1u1, and 10 in my experience. And it's still my go-to image editor for anything that Irfanview can't do.

On my windows 10 machine, I hope I'll be able to run Gimp. I don't know if the Linux Subsystem makes it possible. https://www.reddit.com/r/Windows10/comments/4ea4w4/fyi_you_c...
