It's certainly a good suggestion. Most of us probably have more than one computer nowadays. It makes lots of sense as a backup and way of easily running older software. A virtual OS solution would enable you to work with W7 but it can be a daunting prospect. It took me a long while to understand what to do. There is regrettably unsupported great software that just refuses to work directly with the latest Windows OS. In our case it's Microsoft Home Publishing. The wife loves it - it is intuitive compared with Publisher and that's why we maintain XP.You should seriously consider not using this rig on the Internet for your day-to-day as you are going to be easily infected again. Microsoft is not fixing any new vulnerabilities anymore. You really should have a 2nd machine with a newer OS on it for browsing.
