Ease of Installation
Both products have easy installation processes. The VMware installation had a small flaw, though: It warns against keeping CD Autoplay enabled. I don't run CD Autoplay for security reasons. I confirmed that Autoplay is disabled in my Group Policy Editor (gpedit.msc) before continuing the installation. Figure 1 shows my policy.
Figure 1 Autoplay is off by default.
The installation process didn't enable Autoplay, but the fact that it couldn't sense that it was disabled is unnerving. It's an easy configuration to check. What other installation mistakes might there be?
Overall, though, I think that the two products are equally easy to install, with slight points to Virtual PC for a more comforting installation process.
