While a certain fruit-based company hogged much of the limelight last week by seeing just how much cash could be wrung from fanbois, Microsoft found itself in the spotlight of shame. But Edge-pleading and build-encrypting weren't the only things that happened in the world of Windows.

While Skippy the Windows Insider found himself staring at a Green Screen of Death rather than the promised acrylic (aka blurred) login screen of a new Skip Ahead build of next year's Windows 10, Microsoft kicked off the pre-release trolling of its army of volunteer testers by emitting build 17758 (aka Redstone 5, aka Windows 10 October 2018 Update) first to the fast ring and then, within three days, lobbing the same build to slow ring testers.
