Windows Insiders in the Dev Channel have a new build to install. Microsoft just shipped an update that brings systems to Windows Insider Preview Build 25206. There are a few notable changes in the update, including the ability to use Dynamic Refresh Rate on an external display. It also changes how SMB authentication is handled and includes a long list of fixes and improvements.

Microsoft shared a TL;DR list of highlights for the build in its release notes:

  • The build includes changes to SMB authentication rate limiter behavior.
  • We’ve got a few changes and improves including making the updated “Open with” dialog available to all Insiders in the Dev Channel, some updates for Dynamic Refresh Rate (DRR) and more.
  • This build also includes a set of fixes to improve the overall experience for Windows Insiders.
  • We also added a new known issue for a bug we’re investigating that is impacting a subset of Insiders in the Dev Channel from updating to the latest builds.

Several other changes and improvements shipped with the update, including the option to use Dynamic Refresh Rate on external displays. The feature saves power by changing the refresh rate of a display based on which content is on the screen.

Windows 11 Build 25206 changes and improvements:


  • The updated “Open with” dialog box is now available to all Windows Insiders in the Dev Channel.


  • Windows Insiders can now save power by using Dynamic Refresh Rate (DRR) on external displays! To enable this setting, you must have a 120+Hz monitor with VRR (Variable Refresh Rate) support, as well as a WDDM 3.1 driver installed. To select a dynamic refresh rate, go to Settings System Display Advanced display and make your selection under Refresh rate.
    • Note: To get the latest GPU drivers available for Windows Insiders, check for Windows updates by going to Settings > Windows Update, then select “Check for updates”. To find out what WDDM driver you have, go to Start > dxdiag > Display and look at the Driver Model under Drivers.

File Explorer

  • Search from File Explorer Home will show recent file activity for cloud files in Details View.


  • We’re beginning to roll out a change to suppose the use of clipboard history (WIN + V) on password fields. We are beginning to roll this out, so the experience isn’t available to all Insiders just yet.
