Despite its early praise, Windows 7 might actually boot slower than Windows Vista, according to iolo Technologies. iolo's study found that it took Windows 7 one minute and 34 seconds to become usable, whereas Windows Vista took only one minute, six seconds, reports The Inquirer.
iolo also found that boot times for Windows 7 get worse over time. A 3-month-old machine took two minutes, 34 seconds to boot up. However, Windows 7 did outperform Windows Vista at the three-month and six-month marks. Ina Fried says the results are similar to what CNET News discovered in its testing of Windows 7.
Neither story explains why it gets slower over time.
