Common questions
- What is a zero-day and does a fix exist on day one?
A zero-day has no fix on the day it is found. The service acts once a vendor fix or a mitigation exists.
- How does this differ from monthly patching?
Rapid patching uses an expedite policy to push one security update ahead of the monthly schedule, bypassing deferral without changing monthly policies. Monthly patching has its own page.
- What happens with a restart?
Users get notifications and can restart manually. If not, a restart occurs at the chosen deadline.
- Which Windows computers qualify?
Windows Pro, Enterprise and Education editions managed by Intune qualify. Windows 10 has reached end of support.
- What is CISA's catalog?
CISA calls its Known Exploited Vulnerabilities catalog the authoritative source of vulnerabilities exploited in the wild.
