Reinstalling .NET framework after some problems with a dll *MSVCR100 or something. After searching the internets for solution, reinstalling this was one of them. And oh, preparing to VM Ubuntu and Mint.
Windows Server 2008 R1. WS2008 on Playground decided to deactivate itself, and no force in the universe seems to make it want to activate again. Yay, hours of reinstalling service packs and Windows updates awaits me.
