-Up and Shutdown"> Start-Up and Shutdown
We tested start-up and shutdown times on all our test systems (for complete results, visit www.pcmag.com/xp). We found an interesting trend on the older systems. On PII/233 systems, Windows XP took as long as the old OSs to boot. Even on the PIII/550s, Windows XP took as long as Windows 98 SE and longer than Windows Me. This was mainly caused by the older BIOS. For the 866-MHz systems and up, Windows XP offers a significant improvement in system start-up, mainly because of its parallel-tasking capability. Shutdown, however, doesnt seem to be Windows XPs forte. In most cases, Windows XP took slightly longer than the other OSs to turn off the system.
