Fixing mouse issues with VirtualPC -> VMware images

Microsoft often delivers free-to-test disk images of their products (like, for instance, the new Visual Studio 2010 CTP). These images are – who would have expected that? – in Microsoft’s own VirtualPC format. Luckily, the specs for the disk format are available and you can use the VMware Converter to just convert it into a vmdk (or use it directly, which I can’t really recommend).

Upon installing the VMware Tools, though, you’ll notice that the mouse gets stuck in the lower right corner of the screen if you didn’t remove the VirtualPC tools beforehand. Quite annoying, isn’t it? This comment describes how to solve the problem:

  • Fire up regedit, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetContro lClass.
  • Within the keys under Class look for a value named UpperFilters, containing the value “msvmmouf”.
  • Remove “msvmmouf” from the value and reboot your VM.

Nifty.
