Windows 10 build 17040 now available for download

Windows 10 build 17040 is now rolling out for Fast and skip ahead ring insider members. The new Redstone 4 update comes with new features and other improvements to the OS. With the latest build, you can now Adjust the brightness of SDR content on your HDR display.

In addition, the build also added a new gesture so you can automatically commit your text and clear out the text in the handwriting panel. Check out more details below.

Update: Windows 10 build 17040 ISO files are now available here.

New in Windows 10 Build 17040

Settings Improvements

Adjust the brightness of SDR content on your HDR display: You can now adjust how bright SDR content appears when running in HDR mode on the desktop. On an HDR capable system, you will see a slider in the “HDR and advanced color settings” page under Settings > System > Display. This is one of the improvements to HDR image quality that we have planned based on feedback from Insiders.

Windows now lets you adjust how bright SDR content appears when running in HDR mode on the desktop. On an HDR capable system, you will see a slider in the “HDR and advanced color settings” page under Settings > System > Display.

New Cursor, pointer, and touch feedback section in Ease of Access Settings: Continuing our recent efforts to reorganize this section in Settings, you’ll notice that “change cursor thickness”, “Change pointer size and color”, and “Change touch feedback” have been moved to this new place.

Touch keyboard Improvements

Shape-writing with wide touch keyboard: With the Fall Creators Update we introduced shape-writing input for one-handed keyboard is also now available when using the wide keyboard!

Handwriting panel Improvements

Improved Insertion Gesture: Windows 10 build 17040 updated the insertion gesture (to add space between words or letters) to now be a small caret (see below gif for a demo of what it looks like, along with a cameo of our joining gesture).

A New Commit Gesture: Windows 10 build 17040 added a new gesture so you can automatically commit your text and clear out the text in the handwriting panel. This gesture looks like a 90 degree angle bracketing the end of your text – see gif below for an example of how it works.

Improved button layout for Chinese (Simplified) Handwriting: If you use Chinese (Simplified), you’ll now see a layout similar to the one announced for other languages with Build 17035. The buttons in the handwriting panel are collapsed by default – tap the button with the ellipsis to expand them.

Fixed in Windows 10 build 17040

  • Fixed an issue resulting in checkboxes being missing from certain win32 apps.

  • Fixed an issue resulting not being able to fully remove Windows.old in the last two flights.
  • Fixed an issue resulting in Narrator not saying anything when the candidate bar for hardware keyboard prediction opened. We also fixed an issue where Narrator wasn’t reading the word candidate when the focus moved into candidate bar.
  • Addressed an issue where the “Working on updates” screen was black with a small theme colored box instead of entirely theme colored.
  • Fixed an issue resulting in some Insiders experiencing a green screen on the previous flight with the error BAD_POOL_CALLER.

  • Based on your feedback, the feature to restore applications that have registered for application restart after you reboot or shutdown (through power options available on the Start Menu and various other locations) has been set to only occur for users that have enabled “Use my sign-in info to automatically finish setting my device after an update or restart” in the Privacy section under Sign-in Options Settings.
