Article Content


This article contains information about resolving update progress hanging after clicking "Check" in the Welcome screen for Dell Update or Alienware Update application.

Affected Product:

  • Dell Update 3.1.3
  • Alienware Update 3.1.3


Dell Update and Alienware Update communicates with the Dell Client Management Service to perform the update tasks invoked by the user. When the user clicks "Check" on the Welcome screen, the application calls the service to perform a scan for updates. The service, in turn, will open C:\ProgramData\Dell\UpdateService\Clients\Update\Scheduler.dat to check for any scheduled tasks.

When Scheduler.dat is corrupted, the service gets an error and does not report back to the application which is expecting a response from the service. The application is left waiting and displays the last progress information that it received.


Follow the below steps for the solution:

  1. Close the Dell Update or Alienware Update User Interface (UI).
  2. Right-click the Windows Start Menu, and then click Run (Figure 1).
