BlackBelt - Troubleshooting the Windows OS

Learn to troubleshoot the hardest errors and raise your abilities above others!

The best way to become a great troubleshooter is to learn from the ground up. This course teaches you how the OS really works and how to troubleshoot it effectively.

Sami’s BlackBelt Troubleshooting session has been selected as the Best Session in TechEd North America 2014, TechEd Europe 2014 and TechEd Australia 2013.

This four-day course trains you how to become a better troubleshooter of any environment that runs on Windows. It is applicable to every OS from NT 4 to Windows 10/11 – both servers and clients. Let an excellent presenter and troubleshooter teach you the tricks.

The registration deadline for the training from September 2nd to 5th is August 2nd.

Target audience:

This training is suitable for all administrators who want to deepen their knowledge and troubleshooting skills in Windows. It is also suitable for people who think they know everything about the Windows OS. It is a deep dive course and surely in no way suitable for only the beginners but for seasoned administrators as well (I guarantee you will not be disappointed!).
