Check Your Windows Build Number with Winver and Read What It Tells You
One small dialog answers the questions every watermark fix depends on. Here is how to open it and how to read every line like a technician.

Every route in the watermark story — hide it, unenroll, roll back, reinstall — depends on facts that live in one place: the About Windows dialog behind the winver command. Most users have never opened it, and most guides never explain what its lines mean. This page does both, so the numbers on your screen stop being decoration and start being a diagnosis.
About Windows — reading the winver dialog (recreated)
What each line tells you
Microsoft Windows — Version 24H2FEATURE VERSION
OS Build 26120.XXXXEXACT BUILD
Windows 11 Pro Insider PreviewEDITION + PREVIEW
Expires on 15/09/2026 7:59 PMYOUR DEADLINE
Four lines, four answers. Example values shown — your build number and date will differ, and those differences are the whole point of checking.
👆 The winver dialog decoded. On a stable retail build the expiry line simply is not there — its absence is information too.
1
Open winver in Ten Seconds
Press Windows + R to open the Run box
Type winver and press Enter
The About Windows dialog appears — no install, no admin rights, no internet needed
It is the oldest diagnostic dialog in Windows and still the fastest way to answer what exactly is running on this machine.
2
Read the Dialog Line by Line
Version (for example 24H2) names the feature version family — useful for knowing roughly how current the PC is
OS Build is the exact build number, and the number after the dot is the servicing revision. Support answers, bug reports and exit-route decisions all run on this number
Edition line says Home, Pro or another edition — and on a preview machine it carries the words Insider Preview
Expires on appears only on evaluation and preview builds. When it is there, it is the single most important line in the box
3
Match the Build to the Watermark
The watermark on your desktop and the winver dialog are reporting the same facts in two places. The edition and build in the watermark's text should match the dialog exactly. If the desktop says Evaluation copy and winver shows an expiry date, both are describing one thing: a time-limited build. If the desktop text and winver ever disagree, trust winver — the desktop text can be edited by cosmetic tools, the dialog reads the system itself.
That last point matters more than it looks: after a watermark remover has been run, the desktop goes silent but winver still tells the truth.
4
Take the Second Opinion in Settings
Open Settings → System → About
The Windows specifications section repeats the edition, version and OS build in a copyable form
For the channel, add Settings → Windows Update → Windows Insider Program — build plus channel plus expiry is the complete picture
5
Write Down the Three Facts Before Asking for Help
Any technician — or any comment thread — can help you faster with three facts than with a paragraph of description: the exact build number from winver, the channel from the Insider settings page, and the expiry date if one is shown. With those, the correct route (wait, roll back, reinstall, or simply hide the text) can be chosen in one step instead of five questions.

Only evaluation and preview builds show an expiry line. On a stable retail build there is no expiry date to display, so its absence is good news — it means that build does not run on a clock. If your desktop still shows a watermark but winver has no expiry line, re-check which watermark text you have; Test Mode, for example, is a boot setting and shows no expiry either.
Is a higher build number always better?
No. A higher build number means a later build in the development sequence — on preview channels it usually means newer and less tested, not better. Stability lives on the stable channel, whose build numbers are lower than the preview line precisely because it is not chasing the newest code.
Where does winver show my Insider channel?
It does not — winver reports the version, build, edition and expiry, but not the channel. The channel (Canary, Dev, Beta or Release Preview) is shown in Settings under Windows Update, Windows Insider Program. You need both places for the full picture: winver for the build facts, Settings for the enrollment facts.
