Microsoft has released several "high priority," patches including two for Windows Vista.
Among the four updates Microsoft pegged as "non-security, high-priority" today were the usual monthly revamp of the Microsoft Malicious Software Removal Tool and new signatures for the Outlook 2003 and Outlook 2007 anti-spam filters.
One Vista-specific update was also on the list, as was another that affected both XP and Vista.
The first, dubbed March 2007 Windows Vista Application Compatibility Update, added compatibility "shims" - code that makes an application think it's actually running on a pre-Vista PC - for older Windows titles, including Trend Micro's Internet Security, Windows Server 2003 (SP1) Administration Tools Pack and RealNetworks' RealPlayer 6.0.12.
The second was another revision to the Windows Media Format 11 SDK code. In the associated support document, Microsoft said that the update corrected a problem that some portable music players had in synchronising data with subscription services.
The updates were made available via the consumer-orientated Microsoft Update and Windows Update services, and the enterprise-orientated Software Update Services (SUS) and Windows Server Update Services (WSUS).
