UPDATE 6/10: Windows 10 Insider Preview Fast Build 19645.1 (mn_release) - June 10

Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 19640 to Windows Insiders in the Fast ring.

You can check out our Windows Insider Program documentation here, including a list of all the new features and updates released in builds so far. Not seeing any of the features in this build? Check your Windows Insider Settings to make sure you’re on the Fast ring. Submit feedback here to let us know if things weren’t working the way you expected.

If you want a complete look at what build is in which Insider ring, head over to Flight Hub. Please note, there will be a slight delay between when a build is flighted and when Flight Hub is updated.

General changes & improvements

• Based on feedback, if your Downloads folder is synced to a cloud provider, we are disabling the option to have Storage Sense automatically clear out your Downloads folder on a cycle.
• We updated our login logic, so if your PC is set up so you need to type in your username when logging in, accidentally starting your username with a space will no longer result in an error.

Known issues

• We’re looking into an issue where some devices booting from eMMC storage bugchecked when resuming from hibernate.
• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• We’re working on fixing an issue for a future Insider Preview build where in Settings > Privacy, the Documents and Downloads sections show a broken icon next to their page name (just a rectangle).
• We’re looking into reports that taskbar preview thumbnails aren’t rendering consistently (showing a blank area).

Thanks,
BLB
