If you're an admin, you can deploy a .reg file to users' machines to turn off Coming Soon. To create the .reg file use the following steps.
Copy the following text into the file.
Save the file and change the extension from .txt to .reg.
Tip: To change the extension of a file in the Save dialog, put quotes around the file name, for example: "DisableComingSoon.reg".
Right-click the file you created in Step 3, and select Merge from the pop-up menu. This will create the correct registry key and set its value.
Note: You may have to click Yes to allow the Registry Editor to make changes to your computer.
We are working on a group policy to turn off Coming Soon. This article will be updated with information about the group policy when it's available.
