Microsoft is preparing to release five security bulletins on Tuesday 10 April as part of its regular patch release cycle.
The Windows operating system will receive a four bulletins with a highest severity rating of critical. The remaining bulletin affects a critical flaw in Microsoft's Content Management Server.
Each bulletin addresses one or more vulnerabilities.
Microsoft didn't release any updates in March as part of its monthly patch release cycle.
But the software vendor last week was forced to rush out a fix for a critical flaw in the way that Windows treats animated cursor files. Attackers were actively exploiting the vulnerability, forcing Microsoft to release the patch one week earlier than originally planned.
As always, next Tuesday's update also will bring an update to Microsoft's malicious software removal tool. Microsoft is also preparing a total six non-security updates that are labelled "high-priority".
