Nick White has an excellent post about SP1 on the Windows Vista Blog. Check it out, it lists several reasons why SP1 might not show up in Windows Update. Going the Windows Update route will be worth it because…
- The download size from Windows Update of Windows Vista SP1 for x86 is 65 MB (compared to 450 MB from the Microsoft Download Center).
- The download size from Windows Update of Windows Vista SP1 for x64 is 125 MB (compared to 745 MB from the Microsoft Download Center).
Microsoft has made Windows Vista Service Pack 1 (SP1) available in the Windows Download Center. SP1 will show up as an optional update in Windows Update within the next few days, if it hasn’t already. If you have multiple computers running Windows Vista and you don’t want to wait for it to show up then you can get it from here.
As you can see on that page…
DO NOT CLICK DOWNLOAD IF YOU ARE UPDATING JUST ONE COMPUTER: A smaller, more appropriate download is available on Windows Update.
So, please don’t use this if you are going to apply this to only one computer. I have three so I think my download is justified 🙂
