Yesterday, my Windows Server 2008 R2 laptop was running extremely slow. Eventually, I figured out it was all video related – resizing windows, Snagit, even Outlook opening email. The Aero theme was enabled.
A Google search helped pinpoint it to the Hyper-V role I had recently added. The combination of Hyper-V (the virtualizaton software for Server 2008 R2) and Aero is the problem.
Switching off the Aero theme helped a lot but removing the Hyper-V role is the real answer for now.
I wanted Hyper-V to play around with a
virtual image of Win Server + Visual Studio 2010beta.
