The Windows Vista Service Pack 1 (also called Vista SP1) fixes a range of bugs in Windows Vista. It provides enhanced security measures that will hopefully improve defences against viruses, worms and hackers, along with increased manageability and an improved experience for users.
Vista Service Pack 1 is a large download and can be applied to any version of Windows Vista. However, Service Pack 2 and all subsequently released updates must be installed to ensure that your installation of Vista is secure.The advantage of this full download is that it can be used on any system - plus it doesn't require an Internet connection to install. You can download Vista SP1, burn it to disk and use it on multiple PCs.
