The company issued an advisory on Thursday that it will issue four bulletins for Windows flaws and three for Office, at least one for both Office and Windows will be labeled "critical."
Critical patches are considered the highest-risk category for security problems. As is its practice, Microsoft did not reveal what those security flaws are.
In addition to the seven updates, Microsoft plans to issue an update to the Windows Malicious Software Removal Tool and a non-security-related high-priority update. The company would not say what the high-priority update is related to.
