Microsoft has released Windows 10 Build 20236 to Insiders in the Dev channel. Starting with this build, it is now possible to change the display refresh rate with a new option in the Settings app. There is also a long list of fixes, and a number of general improvements.

What’s new in Build 20236

Change Refresh Rate of your display

You can now go to Settings > System > Display > Advanced display settings and change the refresh rate of your selected display. A higher refresh rate allows for smoother motion. The presented refresh rates can vary with the supported hardware on your device.

Other updates for Insiders

Improving your search experience

We’re rolling out a change to display some of your recent searches when you open Windows Search Box, to make them easy to get back to. This change is rolling out server-side to everyone on version 1809 and higher:

    • The recent list shows the last four items that you’ve searched for and opened from Windows Search Box, which can include apps, files, settings, and direct-nav URLs (for example, like “”).
    • You can remove individual items in this list by clicking the “x” that shows when you hover your mouse over the items.
    • You can disable the Recent feature by turning off the Windows setting “Search history on this device” under Settings > Search > Permissions and History.
    • If you’ve not used Windows Search Box before and have 0 recent items, the recent list will be hidden.
      If you don’t use Windows Search Box often and have fewer than 2 items in the recent list, an educational string will display in the area to let you know what types of items will appear in the list.

This change is rolling out server-side to everyone on version 1903 and higher.

Updates for developers

The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from SDK flights will be archived in Flight Hub along with OS flights.

The Dev Channel, formerly known as the Fast Ring, reflects the latest changes made to the Windows code base. It is a work-in-progress, so the changes you see in Dev Channel releases may not appear in the upcoming feature update. So we can expect to see some features which will never appear in stable Windows 10 versions on Desktop.
Also, it is possible that Microsoft will bring some Windows 10X features to Windows 10 on Desktop. Microsoft is about to add some of Windows 10X's features to get the best of two Windows branches. The company may also replace some of the Desktop feature updates with Windows 10X releases.

If you have configured your device to receive updates from the Dev Channel/Fast Ring ring, open Settings - > Update & recovery and click on the Check for Updates button on the right. This will install the latest available Insider Preview of Windows 10.
