Yesterday, Microsoft announced that SP1 for Vista is now available on computers at retail stores. Meaning that SP1 has been finalized. As most of us know SP1 was available months ago. We have spent some time reading the 55 pages of documentation and here are the reasons you should update:

Improve in the speed of adding and extracting files to and from a zipped folder

Support for creating a single DVD media that boots on PCs with either BIOS or EFI

Hotpatching reduced the number of reboots when updating

New compression algorithm for RDP (Remote Desktop Protocol) reduces network bandwidth by as much as 25-60%

Vista will now report the amount of system memory installed rather than report the amount of system memory available to the OS on 32-bit systems
