I love my Inspiron 7506 2-in-1.  Until recently I have been full of praise for the quality of this laptop and Dell Support in general, even advising others to purchase Dell.

However, as a user of SupportAssist I recently found that Dell.TechHub.DataManager.SubAgent.exe was taking 40% of my CPU.  Browsing this and other non-Dell forums it appears that there is a real issue with this product.

I called Dell and they wished to charge me £48, I declined.  Instead by logging in with an admin account I uninstalled SupportAssist and also renamed all of the Dell executables that consumed large amounts of CPU on startup.

Now I have a laptop which does not sound like a swarm of drones.  

But I have to say I am very very disappointed with Dell Support.
