Microsoft has finally made Vista Service Pack 1 available for public download. Yey! you might say? But whoa there, read on before you rush over to the download page.
There is a rather large list of programs that just break after installation of the service pack, including popular software such as ZoneAlarm and BitDefender.
They have also said that other programs may experience "a loss of functionality" after installation of the service pack. So, before downloading, just make sure you are fully aware of the risks.
Click here for the download. If (like me) you would rather let Microsoft do everything for you, SP1 will be automatically applied to your Vista machine sometime in mid-April.
