Make Vista crash and burn less often. Don’t just twiddle your thumbs waiting for Service Pack 1 to arrive. Take matters into your own hands: One or more of these fixes may solve problems you’ve been having with Vista. None of the fixes has been publicly announced or delivered via Windows Update, so you’ll have to install them manually.

http://support.microsoft.com/kb/929451: A Vista machine may register old IP addresses if certain changes are made to the networking setup.

http://support.microsoft.com/kb/931671: Errors may occur when trying to put your PC to sleep with a live PPP connection.

http://support.microsoft.com/kb/932649: Poor video quality in interlaced mode.

http://support.microsoft.com/kb/940646: Slow performance with 3G WWAN connections.

As well, all users will benefi t from a couple of general Vista performance and reliability hotfi xes that have been pushed out through Windows Update (as recommended updates) and can provide dramatic improvements on some PCs. Check in the Installed Updates section in the Programs and Features control panel to make sure they are installed (look for the KB numbers in the URL). If they aren’t already installed, install them manually.
