How to Fix the ‘DCU.Centennial Windows 10 Pop-Up’ Issue on Dell Computer

The DCU.Centennial is a common popup command that appears on Dell computers. This problem mostly appears because of the last version of Windows 10 (1809) after selecting on the board “deinstall this program” on the “DELL Command” icon.

Fix 1: Disable Dell Command Update

Since the Dell Command feature causes the issue, disabling the update for the feature should fix it. 

  • First, go to the old control panel from windows 7, / program and features (not the new parameter panel)
  • Find the program called “DELL Command | Update for Windows 10” and deinstall it.
  • Next, reboot your computer.

If you need this application, you can reinstall it by downloading it from the Dell Support portal.

Fix 2: Debloater PowerShell Script Solution

7. Select the Remove All Bloatware button in the dialog box. You can also use the Remove Bloatware Regkeys button, but this step is not mandatory.
