You should remove your PC from the Windows Insider Program after the Spring Creators Update releases — here's why, and the steps to do it.
As Microsoft finalizes the Windows 10 Spring Creators Update (version 1803) for its official launch in spring 2018, now is a good time to consider opting out of the Windows Insider Program.

Although the most recent preview builds have introduced a lot of changes and have been getting more stable, as version 1803 gets finalized and Microsoft moves to the next big update, new builds usually don't include significant changes, and they can be buggy and unstable.
If you're not ready for that or want to enjoy the new version for a while, you can gracefully opt-out from the Insider Program without having to reinstall the OS or losing your settings, apps, and files. This is possible because at the end of a feature update development, both preview releases and public releases of Windows 10 are the same versions.
