Final build of Windows Vista Service Pack 2 (update KB948465) ) was released to the public by Microsoft two days ago. I’m not sure if it’s available via Windows Update yet (i don’t use the service) but direct download links for SP2 final are now available. Some of the notable features included in Service Pack 2 include Bluetooth 2.1 feature pack, Blu-Ray media record support, Windows Search 4.0, better streaming capabilities for HD audio and video, a sh1tload of security and reliability updates and many other smaller fixes and enhancements. Both 32-bit 64-bit editions are available.
Although Vista SP2 Final was officially released to the public on the 27th of May, leaked versions have been available on BitTorrent trackers as early as the 13th of May. Warez scene group ZWTISO (ISO division of Zero Waiting Time) even released SP2 integrated untouched versions of Vista ISOs way before the official release.
The effects of installing SP2 on a pirated (cracked) version of Vista is not known. It does not seem to include the hotfix that can detect and disable some BIOS emulation cracks (KB94510). This update has been available on Windows Update for some time but the full list of Vista SP2 features available on Microsoft TechNet does not include kb94510 in the list. I guess pirates are pretty safe in this case.
Anyway you need to have Vista Service Pack 1 installed before you install Service Pack 2. Also, you need to uninstall any pre release builds of SP2 before the installation.
Following are direct download links that point to files hosted on official Microsoft servers. No 3rd party links are included. Vista SP2 standalone installer size is around 350MB.
