Ease of Access

Cursor is a new page in the Ease of Access section where user can now find the “change cursor thickness”, “Change pointer size and color”, and “Change touch feedback” settings.

Windows 10 build 17040 also expands the share-writing feature previously available only with the one-handed keyboard to the wide keyboard.

Also, the touch keyboard has been updated so that the margin between each key is visual only. This change will be noticeable if you accidentally overshoot the key press by just a tiny bit. Previously, it might seem as if key presses were being dropped in this scenario.

Handwriting panel

The handwriting panel now ships with improved insertion gesture (to add space between words or letters). Additionally, Windows 10 incorporates 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.

Additional improvements

The Settings app now allows you to view and manage your activity history, which Cortana uses to let you pick up where you left off on Settings > Privacy > Activity history.

Certain programs will no longer restart automatically after a reboot or shutdown. Now, users need to manually enable “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.
