A reliability and performance update is available for download for Windows Vista Service Pack 1. This specific release targets all Windows Vista editions, provided that they have the first service pack integrated. The update comes with the promise of improving the performance and reliability of the gold version of Vista SP1, and is not addressed at the RTM SKUs of the latest Windows client. Two updates are up for grabs for both the 32-bit and 64-bit versions of Vista SP1. "This update resolves issues that may affect some Windows Vista SP1-based computers. These issues have been reported by customers who use the Error Reporting service or Microsoft Customer Support Services," Microsoft informed.
