Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 18885 (20H1) to Windows Insiders in the Fast ring.
NOTE: Windows Insiders on Build 18362.53 who were unable to update to Build 18875 will need to install Build 18362.86 (KB4497093) *FIRST* before being able to receive today’s build. Build 18362.86 includes the fix needed to update to the latest 20H1 builds from Build 18362.53. If you’re already on Build 18875, this build should come through normally.
Earlier this month, we moved the Fast ring forward to 20H1 and merged the small group of Insiders who opted-in to Skip Ahead back into the Fast ring, which means Insiders in the Fast ring and those who opted-in to Skip Ahead are receiving the same builds for now.
IMPORTANT: As is normal with builds early in the development cycle, 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. If you wish to remain on 19H1, please change your ring settings via Settings > Update & Security > Windows Insider Program *before* taking this flight. See this blog post for details.
If you are looking for a complete look at what build is in which Insider ring – head on over to Flight Hub. You can also check out the rest of our documentation here including a complete list of new features and updates that have gone out as part of Insider flights for the current development cycle.
