Windows 7 XP Mode Hates Intel CPUs?


According to a recent blog post on the ZDNet blog the highly anticipated \”XP Mode\” feature of Windows 7 will not be supported on many of the Intel based CPUs that the OS is being marketed for.

Now a lot of you will remember the whole \”Vista Compatible\” stickers all over PCs when Vista first hit the market. Even more of you will remember the catastrophe when countless graphics cards weren\’t supported by those very same computers. It seems that Microsoft has dropped the ball once again with this whole \”XP Mode\” thing.

The Problem

In order for \”XP Mode\” to run correctly Windows 7 has to create a virtual machine to host the XP computer. Now due to the way that Intel continuously integrates and removes Virtualization technology in its processors there are a multitude of processors that will not be able to use the \”XP Mode.\” Now a lot of you may just be thinking, \”well why don\’t people just buy the right processor?\” The things is that you can’t necessarily tell from the model number whether Virtualization support is integrated or not. If you buy a brand-new PC and pick the wrong CPU, Windows Virtual PC won’t be able to host the virtual machine that powers XP Mode.

An Example

Here’s a real-world example provided by the guys at ZDNet. \”Dell’s Vostro 420 is a well-built, no-frills desktop PC designed for the small and medium business market. The screen grab below shows the current lineup of CPUs that you can choose from when you build this system to order at Dell’s website. Four of the six options support Intel VT; I’ve circled the two CPUs that don’t support VT.\”

\”If you stay with the entry-level CPU, XP Mode won’t run on this PC. So you decide to upgrade the E7400 to an E8500 for $90. Problem solved! Although both are members of the Core 2 Duo family, the E8500 supports Intel VT, whereas the E7400 doesn’t.

But then you realize that for a measly $40 more you can go from a dual-core processor to the Core 2 Quad Q8200. Great idea! Unless you want to use any of those four CPU cores to run Windows Virtual PC, that is. The Q8200, you see, lacks VT support. For that, you need the Q9400, Q9550, or Q9650.\”

As you can see this causes a major monetary problem for the end user as well as a huge convience problem for the average user that just wants to buy a computer and have the ability to use XP Mode without having to do a bunch of research.

The Solution

Thankfully Ed Bott of ZDNet has compiled a quick list to help you decide if your CPU will be able to use XP Mode and so I\’ll pass along the knowledge.
