  • Tried SP1 - 5 BSOD's - will wait until Prod. release

    SP1 downloaded and installed without a hitch, but I had 5 BSOD's with auto reboots in about 5-6 hours of use. Three BSOD's occurred in Medial Player, two in Firefox. Plus 2 playlists corrupted in Media Player along with a sidebar gadget.

    No data lost but they still didn't fix the UAC nags. Why not have a "do not ask me again" with a table (of permissions) like ZoneAlarm? If I say I trust something once, that should be enough. UAC will stay turned off until the nags stop.

    In the short time I used SP1 I noticed no observable deterioration of performance nor any increase. More RAM appeared to be used but not critical. Otherwise, everything worked as it should.

    Uninstalled SP1 - went smoothly and without a hitch. So far all is well again. I'll wait for the production SP1 and if that isn't a major improvement, I'm going back to XP.
  • Not for home/SMB users

    I'd love to see Vista SP1 fix some of the more widespread gripes about Vista (speed? stability? drivers? DRM?)

    But...and this is a big BUT...

    after spending a couple of days testing it on three of my own systems, and being pinged by essentially all my relatives/friends/clients who've been saddled with Vista-infested PCs this year...

    I would take Microsoft at their literal word with respect to the warnings and cautions given about using this on systems people care about. I would NOT recommend casual users, small or midsize businesses, or *any* organization with any variation whatever in their "Vista-capable" PC fleet to touch this with a ten-mile pole until it goes into officially-supported production. There are just way too many things that *will*, not "may", go wrong...go wrong...go wrong....go wrong...

    Ummm....paging Yul Brynner...
