If you're thinking of upgrading your current machine to Vista, the first thing you're going to want to do is check out your current machine to see if it's up to speed. The basic requirements call for a recent CPU, a gigabyte of RAM, and 15 gigabytes of free space on your hard drive. You're also going to want a fast graphics processor, especially if you're going to use the 3D graphics interface, Aero. But there are countless other ways that your system might not be ready for the demands of Vista.
The easiest way to find out if you've got the stuff you need to upgrade is to use the free, downloadable
Windows Vista Upgrade Advisor from Microsoft's web site. When it works correctly, the Advisor goes through all of your system components, telling you what will work and what you'll have trouble with. Of course, I found out that the Advisor is not without its share of problems.
To begin with, it's equal parts sales opportunity and download advisor. As you're waiting for the software to do its scan you get lots of info-ads about Vista in all its different flavors, and you're comparison shopping before you've even done the scan. It's also a big program—a 6MB download.
