Windows updates are important to keep the system up to date. However, if the updates are not configured properly, they can cause unplanned restarts and incur downtime of your Security Center services.
Windows updates are often configured to be downloaded automatically and then installed on the servers and workstations. As a result, a restart of Windows is often required. If servers running major Security Center roles like Directory, Archiver, Access Manager, are configured this way, unplanned restarts result in unplanned Security Center downtime.

Updating Windows regularly reduces the chances of experiencing issues in Security Center.
Each version of Windows has a slightly different way of configuring how it downloads and installs updates. For more information about how to do it with your particular version of the OS, see the Microsoft Support website: https://support.microsoft.com.
