Why am i not able to access newer builds in Windows 11

You likely can't access newer Windows 11 builds because you're not in the Insider Program, your device doesn't meet hardware requirements, updates are paused, or your system is managed by an organization that restricts updates. Check your update and Insider settings to confirm.

In Settings > Windows Update > Windows Insider Program, confirm that the Dev/Beta channel is selected and that hardware requirements are met.
