What’s new on Windows 10 build 17634

Here are all the changes Microsoft is rolling out with this new Redstone 5 preview:


In this flight, the Calendar experience is getting an update to help you find past or future events using search queries like name, location, people, and words in the event.

As you type the query, events that match your search will be more visible, and those that aren’t will be greyed-out. This new search capability only works on Outlook, Hotmail, Live and Office 365 accounts.


The “Cortana Show Me” app designed to help you configure Windows 10 settings now includes support for voice commands. Simply say to Cortana, “Show me how to change my background,” and you’ll get the previous help results, with a new “Let’s go” button below, which launches the guided help experience.

Here are some voice queries to try:

  • Update Windows: Try, “Update my Windows device”
  • Check if an app is installed: Try, “How to see what apps are installed”
  • Uninstall an app: Try “How to uninstall apps”
  • Change your desktop background: Try, “Show me how to change my background”
  • Use Airplane Mode: Try, “How do I turn on airplane mode”
  • Change your display brightness: Try, “Show me how to change my screen brightness”

  • Turn off Windows Defender Security Center: Try, “Show me how to turn off Windows Defender Security Center”
  • Change Wi-Fi settings: Try, “Show me how to change Wi-Fi network”
  • Change your power settings: Try, “How to change when my computer goes to sleep”
