Known Issue Rollback: Helping you keep Windows devices protected and productive

SusanBradleyGeek Thanks for the question.

There are several considerations for when KIR can be used (today):

• Used only for non-security fixes.
• More recent platforms, Windows 10 2004 and newer, leverage KIR more fully. Older platforms have limited KIR support.
• Each fix is evaluated by the developer prior to release to see if KIR is feasible.

Today we don’t publish KIR usage for each fix that goes into a monthly update (LCU). KIR is part of a larger strategy to improve customer confidence in the LCU. The callout to the Windows Release dashboard is to highlight that this is where Microsoft will communicate - not only information about issues but also whether an issue is solved with KIR. KIR-mitigated issues typically release much more quickly than updates to solve regressions, and we are working to expand KIR usage in Windows platforms.
