This is very, very strange. Microsoft announced today that Windows Vista Service Pack 1 (SP1) has been released to manufacturing, which should mean that it’s ready to go. Yet for some reason, they have decided to not make SP1 available until March:
In mid-March, we will release Windows Vista SP1 to Windows Update (in English, French, Spanish, German and Japanese) and to the download center on microsoft.com. Customers who visit Windows Update can choose to install Service Pack 1.
The post talks about some driver issues, but as Long Zheng mentions, it doesn’t sound like they are going to use the extra time to fix those issues. You would think they could at least put the download up at the Download Center. I’m really hoping that SP1 will have a positive impact on performance and battery life and I’m eager to install it!
In other "RTM news" today, Windows Server 2008 was also released to manufacturing! That’s about on schedule. Don’t forget the launch events are happening later this month.

lol even though I haven’t even booted up my vista machine in months, I do look forward to loading SP1 on it.
It’s actually my HTPC of sorts, albeit rather large, fitting inside the Antec Fusion chassis, but the 360 kinda takes care of things these days. :p
Yeah I don’t use my Vista machine much either!
