Earlier in April, Microsoft released a number of security patches for its software products as part of its regular monthly "Patch Tuesday" event. A few days later, the company removed one of those security updates, KB2823324, from both its Download Center and via its automatic update system after receiving reports that it was causing some system errors with Windows users when the update was "paired with certain third-party software."
Today, Microsoft has now re-released that security update with the new version number of KB2840149. In a post on the Microsoft Security Response blog, Microsoft said the update still fixes the 'Moderate' software threat as KB2823324 was supposed to do but should no longer cause those system errors.
Windows users who have Automatic Update set up to receive software upgrades need not do anything to receive KB2840149. People who still wish to update their PC software manually can now download the patch at Microsoft's website. Versions of KB2840149 are available for Windows 7, Windows Vista, Windows Server 2008 and Windows Server 2008 R2.
The next "Patch Tuesday" event is scheduled to take place on Tuesday, May 14th, when we should also see new firmware updates for Microsoft's Surface family of hardware products.
