maybe it seems ridiculous since unix and windows are extremely different on how they look and feel. but it's definitely Microsoft Windows, with some unix programs installed. these unix programs run natively, not through virtualization. these unix programs are compressed into a single zip file called UnxUtils.zip.
extract it with default windows application or winrar or any other applications to a folder. in this case let's simply put it to c drive c:. add that folder to system binary path by invoking "path %path%;c:\usr\local\wbin.
now you can use some of the power of the unix on Windows command prompt. check out by typing ls, cat, touch, vi etc. maybe it's one way for windows users to learn unix system step by step or a different way to enjoy windows. goodluck
