Vista RC1 XP Upgrade Windows Vista RC1 is still doing great for me on each machine that I have it installed on. The first machine that I put it on was my desktop computer that was running Vista Pre-RC1 and I decided to perform an upgrade instead of a fresh install. After the 3-hour upgrade had finished I was able to use Vista RC1 completely. I noticed no issues and was pleasantly surprised. However, because of how long it took to perform the upgrade I chose to do clean installs on my other machines.

Paul Thurrott, however, took an even braver approach by installing Vista RC1 over an XP installation that he had been using for months. Here are a few snippets from the article that he wrote:

I did something scary and thought you might be interested in hearing about it: I upgraded a perfectly serviceable (if dirty) Windows XP installation–complete with months and months of installed applications and data–to see what would happen. The results surprised me.

So after spending (literally) an entire afternoon backing up and even removing some things in order to have enough free hard drive space (Vista Setup demands 15 GB of free hard drive space just to install the OS), I was ready to take my main XP desktop and sacrifice it in the name of science. Well. In the name of curiosity anyway.

I’m happy to report that it went swimmingly. Indeed, I’m writing this review right now in that very system, using the copy of Word 2003 that was installed in XP many months ago. Like most of the incredibly varied list of applications that was installed on this system, Word works just fine, for the most part. Indeed, I’m surprised by how well the whole thing went.

What it didn’t do was happen quickly or painlessly. Beginning to end, the whole procedure took over 90 minutes, well more than three times the amount of time it took to perform a clean install of Windows Vista RC1 on the same PC. It refused to even install until I removed one particularly difficult application, though it curiously had little inhibition about allowing me to keep a number of other applications around, even though it knew they wouldn’t work either. Here’s what happened.

Yes, the application that he couldn’t get to work was Nero 7. I have also run into that problem and right now I lack any kind of good CD/DVD burning software. I assume that Nero is working hard to make their software work because Roxio just released a Vista-compatible version of Easy Media Creator.

Despite his upgrade taking 90-minutes he seems to be quite pleased with the results. My XP installations are all gone and I am only left with Vista RC1 on multiple computers. They all play very nicely together but my biggest complaint is the forced startup sound. It is definitely starting to get on my nerves.
