Installation reports for Microsoft’s new security-focused upgrade range from trouble-free to complete system failures. Our Take: I had one random reboot and one freeze since I installed SP2 this week. The _only_ other time in the past that my XP had crashed was when I plugged-in a SONY external DVD-+RW drive to a USB 1.1 port last month. Except that DVD-RW incident last month, my XP was crash-free for 2.5 years (which might have been a SONY issue, I give the benefit of the doubt to MS). But with the SP2, I had two crashes in 4 days. Unforgivable. SP1 was really solid, can’t say the same for SP2.
