I’m a bit slow posting this but Virtual PC 2004 SP1 has been released; this fixes the highly irritating “sticky” CTRL key problem detailed in an older post and fixes numerous other problems including the bizarre Notepad file truncation bug when you use Shared Folders, it also includes some performance and compression stuff.

SP1 also includes a new version of Virtual Machines Additions so remember to update all of your Virtual PC images

Enjoy!
