Xion Operating System Poll

So, I'm interested to hear from everyone using Xion. What version of Windows do you use Xion on? Make a choice for the Windows version you use the most. Make the choice on 'If I could only use one version, I'd use this one'.
This will just help me with knowing which features I can put in, without breaking other things. I.e. there are some newish functions in the Windows API in certain versions of Windows that I could use to help things, that aren't available in older versions.
Thanks!
