“I want to opt out of the Windows Insider Program on 7/29.” If you decide to opt-out of the program and upgrade to the 7/29 build you will be subject to exactly the same terms and conditions that govern the offer* that was extended to all Genuine Windows 7 and 8.1 customers. This is not a path to attain a license for Windows XP or Windows Vista systems. If your system upgraded from a Genuine Windows 7 or Windows 8.1 license it will remain activated, but if not, you will be required to roll back to your previous OS version or acquire a new Windows 10 license. If you do not roll back or acquire a new license the build will eventually expire.
我来给大意一下吧——
对于不想继续insider的：如果你是从正版win7 or 8.1升级上来的preview，可以保持激活状态，如果不是从正版7or8升级上来的，或者是从（公开密钥）直接安装激活的preview，那就要提供有效的激活码，否则终究版本还是会过期。
