Dell Support Assist; Run Once Then Terminate
Dell Support Assist is a very handy program, on a fresh install of Windows you can install it, run it and it will quickly grab every pertinent driver and BIOS currently available for your system and install them. It is also a great tool if you run into issues with your machine while it is under warranty as a Dell tech can remotely connect to your machine using this software and troubleshoot with you. It is a very easy way to demonstrate failure requiring physical repair or replacement.
On the other hand, as with other remote assistance software it has the occasional vulnerability which nefarious people use to gain access to your computer. If you still have Support Assist for business PCs version 2.1.3 or earlier or a home version of 3.4 or earlier you should either remove it or update it immediately, The Register has the full list and details of the vulnerability if you are curious.
With software you only use very infrequently, you might consider removing it when not in use. That way you can be sure to get the latest version when next you need it.
SupportAssist scans the system's hardware and software, and when an issue is detected, it sends the necessary system state information to Dell for troubleshooting to begin.
