Microsoft has produced two security fixes - one critical - for this month's Patch Tuesday, tomorrow. Both patches are for Windows, the software giant has announced.

Microsoft also will release an updated version of the Microsoft Windows Malicious Software Removal Tool at its Download Centre website. It will not be distributed using Software Update Services, however.

On top of that, two non-security, high-priority patches on Windows Update and Software Update Services, and three non-security high-priority patches on Microsoft Update and Windows Server Update Services will be released.

Last month, Microsoft released one software patch that addressed three critical security vulnerabilities in the way that Windows processes Windows Metafile, a graphics format used by some CAD applications.
