On my laptop I installed a fresh copy of Windows 10 (had to swap the hard drive anyways, so I didn't upgrade from Windows 7). Then I activated the preview builds and got the th2-preview. In this version Windows 10 can be activated directly with a Windows 7 key, this is why I did that.
Up to there everything worked as expected, but now I am getting frequent Bluescreens that I don't get on my desktop PC that runs the regular non-preview Windows 10, so I want to disable preview builds on my Laptop as well and go back to the regular Windows 10. So I go to the Updates-Screen under Settings, and press "Stop receiving preview builds". Now it tells me that I can disable preview builds for a few days, but if I want to disable them permanently, I have to do something else. There is a link where they should tell me what to do. I click the link and then I get to a website, where they tell me, I need to go to the updates-screen and need to press "Stop receiving preview builds", which of course, leads me back to the very same website. So as you see there is a bit of recursivity going on.
Do you know any way to break that loop? ;) Is there any way to stop receiving preview builds?
