Microsoft plans to issue patches for "critical" Windows and Office security problems as part of a regular update scheduled for Tuesday.
The Redmond, Washington-based software company said in an advisory on Thursday that it will issue four bulletins for Windows flaws and three for Office.
At least one Windows and one Office problem are deemed "critical," Microsoft's highest-risk category for security vulnerabilities, according to the advisory.
In addition, the company will update its Malicious Software Removal Tool through its Windows Update service. Over the Microsoft Update service, the company will also release a "high-priority" update that doesn't relate to security.
Microsoft regularly issues patches and distributes them over the Internet. It has been criticised and sued for including a test version of an antipiracy tool, called Windows Genuine Advantage Notifications, along with security updates in April.
