Microsoft plans three patches this week
Microsoft on Thursday warned Windows users to expect three security bulletins May 9, the company's regularly-scheduled second-Tuesday patch day. At least two of the three will include fixes for flaws Microsoft dubs "critical."
Two of the trio affect Windows, while the third will resolve one or more issues in the Microsoft Exchange mail server software. At least one of the Windows' bug fixes will be tagged "critical" by Microsoft, as will the Exchange patch.
At the same time, the company will roll out a refreshed edition of its malware cleaning utility, Windows Malicious Software Removal Tool, and two non-security, high-priority updates via Microsoft Update (MU) and Windows Server Update Services (WSUS). By limiting the non-security updates to those mechanisms, it's likely that they're related to Microsoft Office, or another product which MU supports.
