That said, for anyone who just cannot wait for the final release of SP1, it is available for download from the Microsoft Download Center, linked below. Before you go running off to the Download Center also understand that there are prerequisites required prior to installing SP1 (RC). The complete instructions at the Download Center can be summarized as follows:
- Uninstall any prior release versions of SP1.
- Install all pending Microsoft Updates identified as "Important".
- Click Start > Control Panel > System and Maintenance > Windows Update > “Check for Updates”.
- Restart if prompted.
- Install KB935509, which is the first prerequisite update, and restart the computer.
- If this update results in the presentation of additional Important updates, install those before moving on.
- If you are presented with Ultimate Extras, right-click to hide those updates as unchecking will not let the remaining updates show up.
- If no updates are presented after the previous computer restart, wait ten minutes and scan for updates again.
- Install Update for Windows KB937287 (no restart required).
- Check for updates again and install Update for Windows KB938371. Restart the computer.
- Finally, check for updates once again and install Windows Vista Service Pack 1, KB936330. (As before, if the update is not listed, rescan in another ten minutes.)
It is also worth noting that KB 943899 is not included in Windows Vista SP1 (RC). As described by Nick White in the Windows Vista Blog, this Windows Update
". . . is geared toward improving reliability and performance in Windows Vista and we highly encourage you to install it. It includes:I expect that there will be other additions to SP1 along the way before it is released in final form next month. Anyone who does install the RC will need to uninstall it prior to installing the final version of SP1.
- Improvement of previous issues affecting going into or resuming from sleep/hibernate under some scenarios
- Update to address a previous issue with the disk spindown feature to improve battery life for portable systems
- Up to 15% improved performance of disk I/O (i.e., copying/moving/deleting large files)"
