Today, we are releasing Windows 10 Insider Preview Build 18252 (19H1)
to Windows Insiders in the Fast ring AND
those who have opted in to Skip Ahead. Going forward, Insiders in the Fast ring and in Skip Ahead will receive the same 19H1 Insider Preview builds at the same time. As is normal with builds early in the development cycle, builds may contain bugs that might be painful for some (Which means read the known issues below!). If this makes you uncomfortable, you may want to consider switching to the Slow ring. Slow ring builds will continue to be higher quality. If your PC automatically takes this build before you switch your rings, you can roll-back and then switch rings.
