Microsoft finally released the standalone version of the Windows Vista Service Pack 1 for 32-bit and 64-bit systems. Both versions contain five languages which are English, German, French, Spanish and Japanese. The 32-bit
Service Pack 1 download has a file size of 434 Megabyte while the 64-bit
file size is 726 Megabyte.
This release is intended for system administrators according to Microsoft who wants that “normal” users download the service pack and all other patches through automatic updates and Windows Update. The update should already be available in Windows Update for most users. The download will be smaller than the standalone release because there is obviously only one language that needs to be patched
Users should also take a look at the Knowledge Base article at Microsoft that lists applications that are known to pose problems after installing Windows Vista Service Pack 1.
“Windows Vista Service Pack 1 (SP1) is an update to Windows Vista that addresses feedback from our customers. In addition to previously released updates, SP1 will contain changes focused on addressing specific reliability, performance, and compatibility issues; supporting new types of hardware; and adding support for several emerging standards.”
