As I was looking over the most recent downloads at the Microsoft Download Center I came across a new version of the Windows 7 Upgrade Advisor dated 31 March 2010 and listed as version 2.0.4000.0.

I am not sure what has changed between this update and the last release of this upgrade advisor back in November of 2009 as there is not type of changelog, etc.

As a reminder, the Windows 7 Upgrade Advisor:

…scans your PC for potential compatibility issues and lets you know about your Windows 7 upgrade options. Within minutes, you’ll get a report that tells you if your PC meets the system requirements, if any known compatibility issues with your hardware, devices, and installed programs are found, and gives guidance on what to do to before installing Windows 7 on your PC.

The download is only 8.3MB and can be grabbed at the Windows 7 Upgrade Advisor download page.
