Do you have a version of CleanUp! that runs on (choose your OS) Windows xx?

Yes. All versions of CleanUp! support Windows 95, Windows NT 4.0, Windows 98, Windows 2000, Windows ME and Windows XP. There is nothing in the code that is specific to any of these platforms, so it should run fine on all of them.

CleanUp! 4.0 and 4.5 were developed mostly under Windows XP (Home), and most heavily tested under Windows 98 and Windows 2000 Professional.

CleanUp! 3.0 was developed, from pretty much the same code base as CleanUp! 1.x and 2.x, mostly under Windows 2000 (Advanced Server), and most heavily tested under Windows 98 and Windows 2000 Professional.

I developed CleanUp! 1.0 and 2.0 primarily under Windows NT and tested most heavily under Windows 95 and 98. I also use it myself under Windows 2000 (Professional and Advanced Server) at work. Additionally, I have had reports that it runs fine under Windows ME too.

If you would like to help test CleanUp! on a version of Windows not listed above, then see the thread Help with CleanUp! on newer versions of Windows (e.g. Vista) in the CleanUp! discussion forum.
