Windows Update preview (optional) updates can be avoided by not installing them from the Optional updates available section.
To prevent Windows from downloading and installing this specific preview update (KB5089573):
- Open Start > Settings > Update & Security > Windows Update.
- If the update appears under Optional updates available, do not click Download and install. Optional/preview updates are not installed automatically unless explicitly chosen.
- If it has already started downloading, choose Pause updates for a period (for example, 7 days) to stop further attempts until a later cumulative/security update replaces it.
For managed/business environments using Windows Update for Business, this preview content is normally rolled into the next regular security update, so skipping the preview is supported.
