Build 26120.3281: Windows Insider Dev Channel, February 2025. OneDrive phone-to-PC resume and File Explorer tab restore
Brings a one-click way to resume some OneDrive files from a phone on a PC, plus File Explorer and search changes. It is for Dev and Beta Channel Insiders.
Does it affect you? Applies to: Windows Insider devices in the Dev and Beta Channels. The Beta Channel update is optional for now; Microsoft plans to make these 24H2-based updates recommended later in 2025, after which Beta devices will eventually receive them automatically. Dev Channel Insiders can still switch to Beta while the same-build window remains open, but Microsoft says it is closing soon.
This is a test build for people in the Windows Insider Program. Features in it can change, be removed, or never reach regular Windows releases.
