Redmond (WA) - Microsoft has doled out a few patches to improve stability in Windows Vista, for the second time in as many months.

Microsoft released the security update this week to fix concerns in Vista as well as Windows Media Player and Media Center. The updates "address a small set of reliability, compatibility, stability, security and performance issues," said a Microsoft spokesperson in an e-mail statement.

Vista, originally announced as the safest operating system ever created, has received numerous security updates since its early 2007 launch, including one within less than 60 days after its release.

Also included in the update are enhancements to laptop battery life, wireless network stability, antivirus software, and Vista start-up/shut-down times.

Additionally, Microsoft issued updates to Media Center to address cross-application compatibility concerns, and a vulnerability patch in Windows Media Player.

The security update also addressed a handful of miscellaneous USB stability issues with Windows. The entire set of fixes will available at Microsoft’s website next Tuesday.
