I thought this was funny, and the post is a bit verbose - but hey this appeals to me. 

It looks like Microsoft SoftGrid (aka Softricity SoftGrid) is still finding it’s home within Microsoft.

Today I stumbled across KB 924287 Support policy for Microsoft programs running in third-party virtualization environments..  The KB is definitely aimed at Microsoft SoftGrid’s [supported] ability for virtualization and redirection of:

• Registry virtualization
• File system virtualization
• Kernel components such as semaphores, mutexes, and so one
• Namespace coexistence and redirection
• COM and DCOM objects
• Services
• Fonts
• Initialization (.ini) files

Anyway, if you jump to the bottom of the KB article you will see that the KB applies to the product “Microsoft Virtual PC 2004″ :)

..that I thought was funny.  Poor mis-understood SoftGrid.
