Linux engineers would have no problem learning Windows stuff
Quite the opposite, I work with allot of high caliber Linux engineers , and one of the most difficult challenges is getting them to understand windows and how operate it. When they continually try to 'grep' files instead of using power-shell, 'ls', or even 'nano' a text file. They tend to flock to OSX that offers them and environment that is more like the environment they are used to.
The over all issue, repeated here is that Windows admins are cheaper than Linux admins. Any Linux admin worth their salt is not going to take the low paying desktop job that a college grad might take as a first real world job.
