You can catch up by installing the latest available build for your current Insider channel; you do not need to install every missed update separately.
Update normally first
- Back up important files.
- Open Settings → Windows Update → Windows Insider Program.
- Confirm that:
- The PC is still enrolled.
- The expected Microsoft account is connected.
- The correct Insider channel is selected.
- Return to Settings → Windows Update and select Check for updates.
- Install every offered update, restart, and check again until no additional updates appear.
Windows must be activated, enrolled in an Insider channel, and configured to provide the required diagnostic data before it can receive preview builds.^1^
If no Insider update appears
Identify the installed build and channel:
- Press Windows key + R, enter
winver, and note the version and OS build. - Check the channel under Settings → Windows Update → Windows Insider Program.
If Windows Update reports an error, run:
- Settings → System → Troubleshoot → Other troubleshooters.
- Select Run next to Windows Update.
- Restart the computer and check for updates again.^2^
If the installed Insider build has expired or cannot update normally, use a current Windows Insider ISO for an in-place upgrade:
- Back up important files.
- Download an ISO matching the Insider channel you intend to use from the Windows Insider ISO page.
- In File Explorer, right-click the ISO and select Mount.
- Open the mounted drive and run setup.exe.
- Select Keep Windows settings, personal files, and apps.
- After installation, open Settings → Windows Update → Windows Insider Program and verify the account and channel.
This method preserves files, applications, and settings when the corresponding keep option is available.^3^
If Setup does not offer Keep Windows settings, personal files, and apps, cancel rather than proceeding unless everything is backed up. The ISO may not provide a compatible in-place upgrade path from the installed build or channel. The remaining supported recovery option is a clean installation, which removes files, applications, and settings.^1^
