If you're one of the many folks that wishes Autodesk would put a leash/muzzle on InfoCenter (wscommcntrl.exe, etc.) you should be happy to read this:
"If you're upgrading to AutoCAD 2012, don't forget to also disable InfoCenter (unless you really need it). Just download and install AcadInfoCenterOff to disable it on any version of AutoCAD or AutoCAD LT. If you already have AcadInfoCenterOff installed, you can just run a repair install to apply to a newly installed instance of AutoCAD 2012."
