Security engineering

Microsoft has several resources and teams devoted to optimizing the company’s engineering protocols, addressing compliance, and ensuring customer trust.

Updates and patches

Security updates and patches are released on the second Tuesday of each month. In order to understand the criteria used by Microsoft to evaluate next steps for a reported vulnerability, see the Microsoft Security Response Center’s Security Servicing Criteria page.

As HoloLens 2 is built from the same foundation as Windows 10 and 11, Security updates which are listed for these platforms are addressed in the corresponding HoloLens 2 OS release.

For guidance on managing HoloLens 2 updates via MDM, see Manage HoloLens updates. The operating system update cadence for HoloLens 2 matches that of Windows 10; there are two updates per year, one taking place in Spring and the other in Fall. For more on how devices are secured during OS updates, see State separation and isolation.
