Roll back is just like an infinite loop.

Performed roll back to stable windows 10 from insider 16257, but like previous versions, after roll back windows update insider is still on. This means to me that updating will install 16257 or slow version if I switch version again, and of course rolling back will repeat the process. So how do I turn of insider option back to "join insider program.

PS In the meantime I will not manually update.

You can only clean install 1703 CU version or wait for Autum Creators Update to leav Insider Programme.
