Build 18890 Arrives in Windows 10 Insider Preview. “Hello Windows Insiders, today we release Windows 10 Insider Preview Build 18890 (20H1). This is best Fast Ring Windows Insiders,” Dona Sarkar writes in the announcement.
“We moved the Fast Ring to 20H1 last month and merged the small group of Insiders who opted-in to Skip Ahead back into the Fast Ring, meaning Insiders in the Fast Ring and those who opted-in to Skip Ahead are now receiving the same buildings.”
No new features are available in this build. Microsoft has fixed a number of issues and notes that the Friendly Dates feature it termed for 19H1 will not be rolled out. In other words, nothing notable.
