Vista - Service Pack 2

Service Pack 2 for Vista has just been released. I installed it in about half an hour with no problems whatsoever. Just make sure that Windows Update is right up to date. You will probably be offered a couple of minor updates that you should install. In my case, after I did those installations THEN I was presented with a page advising that there was yet another uninstalled update, and when I clicked on it there was "Vista Service Pack 2". If all is up to date, the install will only download the files that will actually be changed so the package is much smaller and the install is completed quite quickly (about 1/2 hour). If all is not up to date, then the whole service pack is downloaded and the install time is much longer. If, for some reason, Vista Service Pack 2 does not appear you can download the whole thing from the Microsoft site yourself OR wait a few days and see if it turns up. Apparently Microsoft is NOT releasing to everyone at the same through Windows Update.

Here is the correct download site at Microsoft:
