ERROR_BOOT_ALREADY_ACCEPTED

The current boot was already accepted for LastKnownGood

Windows can use a boot verification program to report boot success to the SCM through NotifyBootConfigStatus. After a successful boot, the system saves a clone of the service database as the LastKnownGood configuration. ERROR_BOOT_ALREADY_ACCEPTED means that acceptance step has already happened for the current boot.

Treat the call as a duplicate boot-verification action rather than a service startup failure. Review which component invokes NotifyBootConfigStatus and ensure only the intended boot verifier owns that decision. A retry loop is inappropriate because acceptance is a state transition, not a transient I/O operation. If a product needs to record its own readiness, use its own durable state or service status; do not reuse the OS LastKnownGood acceptance mechanism as a generic health flag.

What to inspect

Trace the component that first reported boot success to SCM.
Remove duplicate or retried NotifyBootConfigStatus success calls.
Keep application readiness state separate from OS boot-acceptance state.
