Microsoft have today released the second service pack for Vista. I recommend downloading it if you’re a Vista user as service packs usually fix a lot of the problems that are common in earlier versions of Windows.
Service Pack 2, the latest service pack for both Windows Server 2008 and Windows Vista, supports new types of hardware and emerging hardware standards, includes all of the updates that have been delivered since SP1, and simplifies deployment, for consumers, developers, and IT professionals.
You can download SP2 at the links below. If you have a new laptop and are unsure if your laptop is using a 32 bit of 64 bit version of Vista go to your Control Panel and then click on System. Under the System section you should see a field called System Type, which tells you type of operating system you are running.
Please note, in order to update Vista to SP2, you need to have installed SP1 already. If you have not already done this, you can download Vista SP1 at the links below :
