The quickest way to tell Windows 10 from Windows 11 is the winver command, which shows the exact edition, version and build. The taskbar is also a clue: Windows 11 centers its icons by default, though it can be aligned left. Windows 10 reached end of support on October 14, 2025. Consumer Extended Security Updates (ESU) now run until October 12, 2027.

Is Your Version Still Supported?
Knowing whether you have Windows 11 is only half the answer; the version matters too, because each one gets security updates for a fixed period. According to Microsoft’s lifecycle pages, Windows 11 Home and Pro versions are supported until these dates:
| Version | Home and Pro support ends |
|---|---|
| Windows 11, version 26H2 | October 10, 2028 |
| Windows 11, version 26H1 | March 15, 2028 |
| Windows 11, version 25H2 | October 13, 2027 |
| Windows 11, version 24H2 | October 14, 2026 |
| Windows 10, version 22H2 | Ended October 14, 2025 (Consumer ESU to October 12, 2027) |
If winver shows a version near the end of its support, open Settings > Windows Update and install the latest feature update when it’s offered.
Find the Rest of Your PC’s Details
Settings > System > About shows more than the Windows version. Under Device specifications you’ll find the processor, installed RAM and System type (64-bit or 32-bit). Under Windows specifications you’ll see the edition, version, install date and OS build. Click Copy in either section to paste the details into a support request.
Can This PC Run Windows 11?
If you’re on Windows 10 and want to know whether you can upgrade, install Microsoft’s PC Health Check app and click Check now. It reports whether the processor, TPM, Secure Boot and storage meet the requirements. If the PC is eligible, the upgrade appears in Windows Update. For the full comparison of versions, see how to check your version of Windows.
