Windows Vista build 6001.18000 is the official RTM build of Windows Vista Service Pack 1. It was made available to MSDN subscribers on 15 February 2008 and released to the Microsoft Download Center and Windows Update a month later, on 18 March.
Service Pack 1 addressed many user complaints by improving the overall performance and stability of the operating system. New features include BitLocker Drive Encryption support on multiple partitions, support for the exFAT file system, DirectX 10.1, and the reintroduction of the ability to choose drives to defragment in Disk Defragmenter.
This update also removed the Search link on the right pane of the Start menu, and the Search option in contextual menus for Windows Explorer folders.
