STATUS_EVALUATION_EXPIRATION
The Windows evaluation period has expired
The documented NTSTATUS is specifically an evaluation-expiration notification. It is not a clock-skew code and should not be treated as a generic activation error. The original status text describes a time-limited evaluation installation that has reached the end of its permitted period.
Preserve the Windows edition, installation channel and licensing state before making changes. Use supported servicing or licensing paths for the installed product. Repeatedly changing system time, editing licensing data, or suppressing the notification does not convert an expired evaluation into a licensed installation.
What to inspect
- Record Windows edition, build, installation channel, and licensing status.
- Confirm the status is from the OS licensing path rather than an application evaluation wrapper.
- Move to a valid licensed installation or supported upgrade path.
