Beta testers have recently gotten their hands dirty with two Windows Vista update packs, and they have Microsoft to thank. Now we have the testers to thank for leaking the the update packs to the public.

While not officially considered Service Pack 1, the two packs are known as the Performance and Reliability Pack and the Compatibility and Reliability Pack. DownloadSquad reports the packs should become officially available to the public on August 14th, but an unknown source, probably the testers, have released the packs to the public. The packs are available at Neowin, but last time I checked, the download links were broken. Don’t worry though, the files are also running wild via P2P torrent networks.
