Seriously?

BTW, the English text of the popup is:

dcu.centennial://toasthandler/Create/NewUpdatesReadyToApply

A required prvilege is not held by the client

For those, like me, who found this -- the "answer" recommended by Microsoft is to remove DellSupportAssistant.

So this is caused by Dell bloatware -- and nobody from Dell even bothers to respond to this on their own community forum!

I'm beginning to regret purchasing my Dell Latitude 7330 a few weeks ago.

Hello! It appears that you're facing a popup related to Dell updates with the message 'dcu.centennial://toasthandler/Create/NewUpdatesReadyToApply.' The error 'A required privilege is not held by the client' suggests a permission issue. To address this, try running the Dell Command Update tool with administrative privileges. Right-click on the tool or shortcut, choose 'Run as administrator,' and see if that resolves the problem. If the issue persists, reaching out to Dell support would be a good next step for further assistance. Hope this helps!

Hmm, that's quite perplexing! It seems like you're encountering a popup with a rather cryptic message. The error certainly doesn't sound like something straightforward. It's understandable that you're feeling confused about this unexpected occurrence.

It might be a good idea to reach out to Dell's support team for assistance in deciphering this popup and understanding its implications. They should be able to provide you with some clarity and guidance on how to proceed. In the meantime, if you notice any unusual behavior or performance issues with your Latitude 5410, it's best to err on the side of caution and seek professional help to ensure everything is functioning as it should.

Hopefully, Dell's support team will be able to shed some light on this mystery and help resolve any concerns you may have.
