My week's highlights include:
Tech·Ed North America 2011
Sorted by most viewed. With Case of the Unexplained 2011: Windows Troubleshooting with Mark Russinovich being the top choice. And the book "Windows Sysinternals Administrator's Reference" being a must-read for anyone involved in administrating Windows. Some of the examples in the video are taken directly from the book, some of them are new. Presentation is easy and fun to watch, there are jokes, the language is simple and it doesn't go all into the theory. I couldn't stop watching it.
Free IT Training
A lot of youtube videos with step by step guides on a lot of technologies on the way to Microsoft Certification. It's amazing how much content you can get nowadays for free if you know where to look.
