Patch Tuesday
The second Tuesday of the month, when Microsoft releases regular security patches for its products.
What does it mean Patch Tuesday?
Patch Tuesday is the established monthly schedule for releasing updates for Windows, Office, and server products. It allows companies to plan maintenance predictably.
After updates are released, attackers quickly analyze which vulnerabilities were closed and target systems where patches have not yet been installed.
Therefore, it is sensible to schedule a maintenance window within a few days of the release, following a preliminary trial on a test group.
Practical examples
The company has a maintenance window every third Thursday of the month: patches have already been tested on test devices by then, and servers are updated in the evening.
Business relevance
A predictable schedule enables planning and prevents updates from being constantly postponed due to operations.
Common mistakes
Typical mistakes include delaying monthly patches, waiting for a "quieter period", and the absence of a procedure for out-of-band patches outside the regular schedule.

Frequently asked questions
- Do we need to install patches immediately?
- Not immediately, but within days; as soon as possible for critical vulnerabilities.
- What are out-of-band patches?
- Patches released outside the regular schedule due to actively exploited vulnerabilities — these should be installed immediately.
- What about computers that are turned off?
- They receive patches at the next startup; coverage should be monitored in the report.
