Windows 7, Virtual PC and the double SP1

While trying to install the Virtual Machine Additions in Windows 7 beta running in Virtual PC 2007, I found out that Virtual PC 2007 has two service pack 1 - the older one upgrades it to 6.0.156, the newer one to 6.0.192. If you try to install the VMA that came with the older SP1, at reboot you will be greated by a BSOD telling:
A problem has been detected and Windows has been shutdown to prevent damage to your computer.
Fs_Rec.sys
The driver mistakenly marked a part of it's image pagable instead of nonpagable

Making Delphi work with DCOM

In the past few days I had many troubles making our application work when the client was installed on a PC outside the application domain. It was due to several Delphi 2007 issues with DCOM.
