But Microsoft doesn’t offer new Windows updates to all PCs at once. When Microsoft provides the update to your PC, it automatically installs itself. If you see a higher version number than 21H1 on your system, you’re likely running an unstable Insider Preview version of Windows. In the screenshot, the PC is running Windows 10 version 20H2. Rest assured that, if the Settings app says you’re using version 21H1, you have the latest version.įor example, if you see “2004” here instead, you’re using the May 2020 Update. Note: 21H1 is a smaller update, so the “Installed On” date may not be updated here and may show a date in 2020 instead of 2021. If you see a lower version number, you’re using an older version. A version number of “21H1” indicates you’re using the May 2021 Update.
