DSA provides other utilities while DCU only pulls driver and BIOS updates. DSA or DCU are useful when you're performing a clean installation, while DSA could be of some benefit for system maintenance. I run DSA on all my Dells but one. The Precision M3800 I've got, freezes seconds after logging in. The fans blow loud and the system is unresponsive for a second or two. After that it goes back to normal operation. Uninstalling DSA stops this behaviour and CPU activity calms down to idle around 1 percent. But with DSA installed, it runs between 2 to 5 percent. I don't know why this happens but it is as if DSA gives the M3800 indigestion. DCU runs fine however.

I have uninstalled and reinstalled SupportAssist several times and the Task in Progress problem persists. Are there any other ways this problem could be solved?
