Startup Accelerator?

What is the Startup Accelerator, and how can I stop it?

From AutoCAD's help files...

Runtime process that can accelerate the initial startup

If you do not want this automatic process to run at startup, you can turn it off.

To turn off the process, on the Start menu (Windows), click All Programs (or Programs) > Startup, then right-click Autodesk Product Name > Startup Accelerator and click Delete.
