Ok here a short brief about windows XP mode in windows 7.

What is Windows XP mode (in Windows 7)?

It is a Virtual OS which you can run it on windows 7. Its is free and allow you to install games and software which incompatible with windows 7. Windows XP for me still the best OS, so it may be one of the step from Microsoft to make user upgrade to windows 7 with this utilities.


Can Your PC Run Windows XP Mode?

Windows XP mode is only limited to PC which the processor support the Virtualization technology. If your processor doesn't met the requirement you can't install this program.

How do i check?

You can check either your processor support virtualization technology or not by downloading Intel® Processor Identification Utility and also Microsoft® Hardware-Assisted Virtualization Detection Tool

Installation:
You must install Windows Virtual PC first and then Windows XP Mode



After installing both programs you may need to restart, after all installation finish.
Click start - programs - select XP Mode and lets it run the configuration, your win xp mode is ready.

This might be helpful if you need recovery disk for your windows vista.

Quoted from:http://www.pcworld.com/downloads/file/fid,71039/description.html

It looked like Microsoft was finally going to do the right thing. Beta versions of Vista SP1 came with a modern equivalent of the old Windows Boot Floppy--a Start Menu option called "Create a Recovery Disc" that burned a Windows PE-based emergency CD. Alas, Microsoft removed that feature before SP1 shipped, but not before NeoSmart turned the disc into an .iso file and made it available on their site.
Running on the Vista version of Windows PE, the Recovery Disc is basically a Vista installation disc minus the install files. It even has an "Install now" button that asks for a Product Key before failing. You're better off clicking the Repair your computer button. Among its Vista-only options are a tool for diagnosing and fixing startup problems, a version of System Restore that uses restore points on the hard drive, the restore portions of Vista's backup program, and a memory diagnostic tool.
Note: This link takes you to an external Web site, where you can download the latest version of the software.

There are a lot of driver missing when downgrade from xp to vista and 7 unknown devices is quite a popular topic discussed. And there are also other driver such as co processor. When downgrading for me the essential driver is chipset, sound, vga, wireless, bluetooth and card reader. So what to do with missing driver, for me if nothing wrong with your laptop no need for you to update the driver because you already have the essentials drivers.

Extract the files and  right click on machine.inf select install.

It isn't hard to find your driver if you know the model to find the model of your laptop is not difficult: look at the picture below. Normally for laptop you will find white stickers on the back of the laptop and there you can find the model. So by refer to the picture below your model is no 1 arrow.

1	Model Number (shown in area below the bar codes)	dv9095xx	The Model Number is unique to the hardware components, and is the most useful for finding drivers and support content.
2	Product Number (p/n)	RQ877AS	When using the Product Number to find a part or driver, enter only the letters and numbers before the # sign.
3	Product Name (Product)	HP Pavilion dv9000	The Product Name (also seen on the front of your notebook) is not useful, as there may be duplication across several PC models.
