Microsoft Pulls Windows 7 Bulldozer Performance Patch Following Complaints

Just a week after its release, Microsoft has pulled a patch for Windows 7 and Windows Server 2008 designed to improve the performance of the operating systems on AMD's Bulldozer platform.

Released last week, the patch was designed to take advantage of new features on the Bulldozer architecture for which the command scheduler in Windows was not adequately tuned - offering a 10 to 15 per cent performance improvement on the new chips.

Sadly, the company has been forced to withdraw the hotfix - which was a manual download, and not provided for automatic installation via Windows Update.

According to HardOCP, the patch was published prematurely and only included half of the planned performance improvements. The result: many users reported that the installation of the patch had resulted in lowered performance on Bulldozer systems.

As a result, the patch has now been pulled, with Microsoft working on an updated version containing both of the planned performance-pumping program portions.
