Hi there
xp mode runs like a "one legged dog on a perfectly smooth icepond" -- even a lake of thick molasses would run faster.

If you really need XP it's best to use software "fit for purpose" lkle VBOX or vmware with a complete XP install --although of course here you lose the "Free" XP you get with XP mode.

However IF you have an old XP install disc anywhere (has to be retail --OEM one won't work) then install an XP VM from scratch under vmware / vbox.

Both sets of software Do now support a reasonable amount of desktop integration including print support --not quite as much as XP but does it really matter.

The latest version of vmware software supports 3-D, DVD playing support and you can run your VM in the background.

Performance wise on the machine you've got you'd get about 95% Native speed too.

XP mode is a real dog --was only introduced as a sort of half measure to assist in W7 migration -- however my experience has been if you really need to run legacy apps and hardware (I do quite a bit) then only a proper XP VM will do.

Also you can shut it down when you don't need it -- less load on the system too.

What OS is installed on the 6Mhz VPC?
I have the same problem, XP Mode works great but I have 32bit Win7 on another VPC and it shows 6Mhz like yours and runs slow as. From the small amount of research I did I came to the conclusion the 6Mhz means nothing and it was the lack of performance of my host PC (see my system specs), but after reading your post #3 I may have been a bit hasty in my conclusion so I hope someone can help you and me.
