How to Change Windows Insider Program Channel in Windows 10

Hello Andy,

Have you already tested setting this using a .reg file in the tutorial to see if it may help make it stick?

Yes I tried that Shawn, the setting still reverted to RP Ring.

I've spent several hours on trying to sort this problem out and to be honest I can't see a way round it. Running Brink's reg file for the Slow Ring setting creates the registry entries fine and the setting is retained through every reboot. However as soon as Settings/Update & Security is opened up the WIS registry entries change back to RP. Short of doing a clean install I'm at a loss.
I'm going to stay on RP Ring until 19H1 is released and see if that sorts it out, if it doesn't then I'll clean install.

Update

I spent another hour tonight trying to find a solution but ended up a broken man. I'm defeated
