Check Windows Activation Status Using slmgr Commands
Is this Windows genuinely activated forever, or is it running on an expiring arrangement that will one day show the activation watermark? Settings gives a short answer — slmgr gives the full truth.

slmgr is Windows’ built-in Software Licensing Manager — the official tool behind activation. Its three report switches answer the three questions that matter: is this copy activated, is the activation permanent, and what kind of licence is it. This matters most when buying a second-hand PC or after a suspiciously cheap "lifetime activation" — the difference between permanent and expiring is written right here, and no screenshot of the Settings page can fake it.
Windows Script Host — slmgr /xpr result
Windows(R), Professional edition
✅ The machine is permanently activated.
⚠️ The warning version you do NOT want to see:
"Volume activation will expire 24-08-2026 11:30 AM" — this copy runs on a temporary organisation licence and will deactivate when the timer ends.
👆 The one line that settles every activation question. "Permanently activated" is the genuine answer; an expiry date means a temporary activation.

The Verdict — slmgr /xpr
Open Command Prompt or the Run box
Type slmgr /xpr and press Enter — a small dialog appears after a few seconds
"The machine is permanently activated" — this is a genuine, non-expiring activation. You are done
An expiry date instead means the copy is activated through a volume or KMS arrangement for a limited period. On a personal PC that almost always traces back to an unofficial activator or a seller’s trick — it will deactivate when the date passes or the counterfeit server stops answering

The Licence Summary — slmgr /dli
Run slmgr /dli for the short report
Read the Description and License Status lines. The channel word is the key detail:
Retail — a licence bought separately; it can usually move to a new PC
OEM — the licence that came with the PC from its maker; it belongs to that motherboard for life
Volume (KMS or GVLK) — an organisation licence. On a home PC, this word is a red flag worth questioning
3
The Full Report — slmgr /dlv
Run slmgr /dlv for the complete record — activation ID, installation ID, the KMS server name if any, and the remaining grace period
A remaining grace period counting down in days means the copy is not yet properly activated at all
Cross-check with the simple view: winver shows your edition and build, and Settings → System → Activation shows the plain-language status
Buying a used PC? Run /xpr in front of the seller. Ten seconds, and the activation story is settled with evidence
🛑 An honest line about activators: this guide deliberately shows checking tools only. Free "activator" programs that promise lifetime activation are the single most common source of the expiring volume activations above — and they frequently carry malware. A genuine licence, even an affordable OEM one from a reputable seller, is the only activation that stays permanent and safe.

Settings says Windows is activated — why check with slmgr too?
Because Settings only says activated or not; it does not show whether the activation expires. slmgr /xpr reveals the expiry date on temporary volume activations that Settings displays as simply activated — the difference appears months later as a watermark and deactivation.
What does it mean if my licence channel is Volume KMS on a home PC?
KMS licences belong to organisations whose own server reactivates their PCs regularly. On a home PC it usually means an unofficial activator pointed the machine at a third-party server. It may work for months, but it is not a genuine personal licence and can stop without warning — plan on a proper licence.
Can slmgr fix or remove the Activate Windows watermark?
slmgr reports and manages genuine licensing; it has no switch that legitimately removes the watermark from an unactivated copy. The watermark disappears when Windows is activated with a valid product key — enter it in Settings → System → Activation. Any tool promising otherwise is an activator, with the risks described above.
