Note it takes longer to install Service Pack 1 than it does Vista! If you have a Windows Vista DVD, instead download the correct Service 1 and Service Pack 2 file (below) and install these immediately after installing Windows Vista.Note: The Windows Vista setup files are very large (~2 GB each) and require the use of high speed internet to download. Any system that can run Windows Vista can run Windows 7. If you can afford it I would recommend upgrading to Windows 7.
