How to Change the Default Quiet Hours in Windows 10
Have you ever wondered why you can only turn Quiet Hours on or off in Windows 10, but not set the actual hours you want? Windows 8 introduced the idea of Quiet Hours—Windows’ version of Do Not Disturb, where notifications won’t notify you during those hours. And in Windows 8, you could configure Quiet Hours to turn off and on at certain times. For some reason, Microsoft did away with that control in Windows 10, leaving you with only an on/off switch and the impression that everybody must have the same hours off. By default, Windows 10 sets Quiet Hours from midnight to 6:00 am, with no way to change them in the UI. The good news is that if you’re willing to dive into the Windows Registry to make a couple of quick settings changes, you can change the actual times that Quiet Hours uses.If you are looking to set the time during which quiet hours should remain enabled automatically then please follow these steps.
Change Quiet Hours by Editing the RegistryPress the Windows Key + R and type in 'regedit' to open the Registry Editor or click Start and type “regedit.” Press Enter to open Registry Editor and give it permission to make changes to your PC. In the Registry Editor, use the left sidebar to navigate to the following key:
Next, create a new subkey inside the CurrentVersion key. Right-click the CurrentVersion key and choose New > Key. Name the new key QuietHours. Now, you’re going to create two new values inside the new QuietHours key. Right-click the QuietHours key and choose New > DWORD (32-bit) Value. Name the new value EntryTime. Create a second DWORD value in the QuietHours key and name it ExitTime.
The EntryTime value specifies the time that Quiet Hours begins and the ExitTime value the time that Quiet Hours ends. Open each value in turn by double-clicking it. In the properties window for each value, set the “Base” option to “Decimal.” In the “Value Data” box, you’ll type the number of minutes after midnight that you want to trigger the event. So, for example, you might set the EntryTime value to 120 for 2:00am (120 minutes after midnight) and the ExitTime Value to 600 for 10:00am.
You can now close Registry Editor. The changes take place immediately, so there’s no need to restart your PC. The new Quiet Hours start and end times should be in effect from now on. To reverse the change, just follow the same steps and delete the QuietHours key you made, which will also delete the two values you created in that key.
