The InfoWorld Test Center takes a surgical look at both Windows Vista SP1 and XP SP 3. “Windows XP Service Pack 3 has been the recipient of copious undue attention,” Randall Kennedy writes in Test Center guide to Vista and XP service packs. “After all, it’s just another compilation of patches and minor tweaks — for an obsolete OS, no less.”But with many IT department considering bypassing Vista, the release of Service Pack 3 takes on new importance in that it “may be the last Service Pack [IT] sees for their chosen platform before Windows 7 arrives in late 2009.” The verdict for both is to deploy — one is even a “must-have,” according to Kennedy.
