Reset VSS Writers

VSS writers are application-specific components for Microsoft's Volume Shadow Copy Service, which ensure the consistency of application data when a shadow copy is created.

Lync Automation

We're using Microsoft Lync 2010 at work, and I find it quite annoying that the software keeps resetting my status to "available" when I don't want it to. So I started looking for a way to automate setting the status back to "busy".

Having to install Visual Studio, SQL Server Express and the Silverlight 4 Tools seemed a little overkill to me, though.
