Microsoft decided to migrate Skip Ahead into the Fast ring
According to the Windows official blog, the company’s latest release of Windows 10 Insider Preview Build 19018 has been pushed to the user on both Fast Ring and Skip Ahead. Starting with this version, Microsoft will completely cancel the Skip Ahead channel and will not be available later. This version combines Fast Ring and Skip Ahead.
Microsoft writes:
Starting today, Windows Insiders who have opted into Skip Ahead are being migrated back into the Fast ring. This means that Skip Ahead will no longer be reflected under Settings > Update & Security > Windows Insider Program. Going forward, we will not be offering Skip Ahead as an option for Insiders to sign-up for. Our goal is to provide everyone in the Fast ring the freshest builds at the same time.
IMPORTANT: As is normal with pre-release builds, these builds may contain bugs that might be painful for some. If you take this flight, you won’t be able to switch Slow or Release Preview rings without doing a clean-install on your PC.
