Microsoft releases Windows 11 Preview Build 23536 and 25941

It’s Thursday and Microsoft has, as expected, released two new Insider Preview builds. Today Microsoft released Windows 11 build 23536 to the Dev channel and Windows 11 build 25941 to the Canary channel.

The new Insider build for the Dev channel focuses on bug fixes while the new build for the Canary channel brings some new features as well. Both are part of weekly updates so don’t expect them to be big updates.

Windows 11 build 25941 brings option to enable Dynamic refresh rate via toggle. Enabling the dynamic refresh rate will adjust refresh rate according to the open screen which will help save battery. Also the new update brings awareness to the Refresh rate limitations with display resolution.

Here are all the changes for both builds.

Windows 11 build 25941 (Canary Channel) Changes:

Changes and Improvements


  • In this Insider Preview build, you may notice that there have been some changes in the advanced display settings page via Settings > System > Display > Advanced display. Dynamic refresh rate can now be enabled via a toggle. After being enabled, Windows will then dynamically adjust the refresh rate up to the selected rate to help save power. Click here for more information on Dynamic refresh rate.
  • Additionally, we’ve made small changes to help bring awareness to limitations (related to the display or the cable being used) that may not allow you to set a high refresh rate while being on a high display resolution. When selecting a refresh rate, you may notice some refresh rates will show an asterisk. That means that in order to select that specific refresh rate, the display resolution will need to be changed to one that supports the selected refresh rate. This behavior happens when there are limitations due to the cable or the display’s capabilities and is not new, but we wanted to make sure you were aware of it.


  • Building off the Cast improvements introduced with Build 25926, we have updated the Cast flyout in Quick Settings with additional support for you in case you face any trouble discovering nearby displays, fixing connections, and more.
