I realize that my copy of Windows 7 is only the Release Candidate (RC) version, but I can't imagine that the upgrading feature will improve that much in the final version of Windows 7. If you've been following my blogs, you know that I have a Lenovo Thinkpad X200 Tablet PC. I also have 2 different hard drives, so I decided to do a little experiment. On the first HD, I did a clean install of Windows 7. On the second HD, I loaded Vista, and then upgraded to Windows 7. How can I afford to do all this and maintain my productivity? I can do this at home because I have a few other computers that I can use while I'm running my little experiments.
If you've done many operating system upgrades, you know that you always get better system performance (speed, efficiency, stability, etc.) when you do a clean install. However, if you do a clean install, you have to reinstall all your applications, customize your settings, etc. It can be a real hassle. At the end of the day, you're always better if you do a clean install. An upgrade can cause its share of problems. According to Microsoft, Windows 7 is only considered a "minor upgrade" from Windows Vista. So, you'd think that an upgrade should be relatively straight-forward, no? Perhaps that's the case if you hardly have any applications installed. In my case, I have quite a few and here's what I found:
- Slower overall system performance on the "upgrade" vs. the clean install. Not a surprise.
- Slower boot-up times on the the "upgrade" vs. the clean install. It still boots faster than Vista, but it's about 20 seconds slower compared to the clean install.
- Some funny things happening with the fingerprint reader and touch screen calibration. More to come as I experiment. I realize that many of the drivers may not be ready for this machine. Plus, some of the ThinkVantage utilities are probably not compatible with Win7 at this point.
