Not at all. The Windows OS now has command line accessible management points that are similar to Linux. There is still a great deal of difference in their management models (I blogged about this a while back - http://blog.serverfault.com/2013/06/03/cross-platform-config...)
That I was hired as a Windows specialist was so that we can go deeper on the OS side and the PowerShell side, just as we have a Linux expert to go deeper on the Linux side. Our sysadmin team was just more tilted with experience on the Linux side (though you wouldn't know it - as almost everyone I work with would qualify as a senior admin in any Windows shop in the world).
I am glad to see that there are comparable capabilities in the modern Windows world and will dig into the WMI side of things next time Windows admin tasks come up.
I'm glad its working for you, I use stackexchange daily and am generally quite happy with it!
