I had the 'honor' of rescuing yet another victim of a pre-installed software nightmare. A new co-worker was working with his notebook (a Hewlett-Packard, recent vintage, less than a year old with Vista Home Basic installed).
The complaint? Minimum five (yes, FIVE) minute boot time from power-on to desktop interaction.
After a cursory examination, I found that it wasn't a hardware problem, nor was it due to memory limitations: the system had 512MB RAM, Vista was using just over 300MB with no other applications running (yes, that's a lot, but this is Vista, after all).
