Hey guys. 

 

I'm using my Inspiron 13 7000 Series 5447 2-in-1. In late 2018 the power brick broke, and got a new one a weeks ago. Turned it on and it ran fast and responsive. Then I decided to do a Windows refresh to free up some space and made a Windows update, and my fast and responsive computer after that went slow to a crawl, sluggish, unresponsive, freezing. Can't use it. 

 

While I was trying to use it, Windows showed a notification saying that the process "DU.Classic" had stopped working, and then my computer started working fast and responsive again. It has happened twice, and my computer gets back to a somehow normal speed again. It stops semi-freezing all the time. I looked it up, and it has something to do with Dell updates. I searched for it in Task Manager but it doesn't show up there. 

How can I remove this program or how can I fix this? Thanks.
