I was asked recently if I’ve ever gone through any of the Microsoft Virtual Labs – oddly enough I haven’t, but there are a wide variety of  labs available:

TechNet Virtual Labs for IT Professionals
MSDN Virtual Labs for Developers.

If you are interested in test driving some features of a Microsoft product or want to gain some hands-on experience without spending money on training, then today is your lucky day…

All Virtual Labs
System Center Virtual Labs

Happy learning!!!
