Hi -
I would suggest SysInternals AutoRuns, free from Microsoft TechNet.
http://live.sysinternals.com/autoruns.exe
Download it and SAVE to Documents. RIGHT-click on
autoruns.exe, select "Run as Administrator". Allow it to scan (status - lower-left screen). Click on "Logon" tab, look for Dell Registration - or similar entry. Un-check the box. Doing so will disable it. Should you desire, you can always re-check the box making it active again.
Regards. . .
