I have made a page that keeps track of anyone who wishes to be a tester for a particular version of Windows. Here is the page: http://wiki.qemu.org/Testing/Windows
If there is a version of Window you would like to help test in QEMU, please contact me with the email address you wish to use and the version of Windows you wish to support. Your information will be added to this list. With this list someone who makes a patch may need your help ensuring the patch is compatible with your supported version of Windows. Here are all the versions of Windows I have up so far: Windows 3.1 Windows NT 3.1 Windows NT 3.5 Windows 95 Windows NT 4.0 Windows 98 Windows ME Windows 2000 Windows XP Windows Vista Windows 7 Windows 8 Windows 10 ReactOS
