I’ve been beta testing v1.5 of OneCare for several months on various Vista configurations as v1 is not supported on Vista. I also purchased a OneCare subscription last April for my XP machines. Based on the Windows Live OneCare blog, version 1.5 availability is expected in time for the big Vista launch in 11 days, 11 hours, 52 minutes and 29 seconds (approximately), but I’m thinking that it soft-launched for two reasons. Remember that I got my new Q1P yesterday, so one of the first things I did was hit up the OneCare site.
When I did that yesterday, I got a message along the lines of: the site is down for maintenance but will be available soon, try again later. I tried several times, but got the same message, which raised an eyebrow and indicated something was up. I just tried again on Samantha, the Q1p, and was able to access the site as well as download OneCare on XP. Since I got the screenshot above from Samantha, I’d say that the Windows Live OneCare team is ahead of schedule as I clearly have version 1.5 running on XP.
