Microsoft has released the Windows 10 Insider build 19635 for Windows Insiders in the Fast Ring. As this has been the case in the past couple of months, this is another minor update that fixes a couple of issues related to LTE connectivity, the Settings app, and cameras.

You can check the full list of fixes and known issues below:


  • We fixed an issue resulting in the apostrophes in the Location not available dialog, Mount File dialog, and File Explorer folder options text not being displayed correctly.
  • We fixed an issue where the Work or School account > Allow Windows Search to provide… toggle under Search Settings could be unexpectedly disabled.
  • We fixed an issue resulting in cellular data not working on certain devices.
  • We fixed an issue that could result in Settings crashing when changing display orientation or resolution.
  • We fixed an issue resulting in some Insiders seeing a large number of “Program Compatibility Assistant Service stopped working” critical events in Reliability Monitor.
  • We fixed an issue that could result in constant display flashing on certain devices.
  • We fixed an issue with the camera on certain devices showing unexpected artifacts.

Known issues

  • We’re looking into an issue where some devices booting from eMMC storage may bugcheck 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).

If Microsoft is still not giving the “21H1” label to these new Fast Ring builds, the company previously mentioned in a blog post that Fast Ring Insiders would get their first 21H1 bits next month, though the company later deleted any mention of that June date. Anyway, now that the Windows 10 May 2020 Update has started rolling out to the public, the company can now focus on future Windows 10 updates, and 21H1 is expected to be the next major release that should follow a minor 20H2 update later this year.
