All this makes sense and I followed the instructions. I now have a feature in this Windows XP Media Edition. I am a user in the Administrator group but when I use msconfig and after I uncheck the sprtcmd.exe in the Startup tab, I get the message that I must be an Administrator. Well, I checked again and I am on this home machine. Any suggestions? By the way, Dell just posted today the solution which is to go to Microsoft and install:
SPRTCMD.EXE is a file used by Dell Support Center. The error occurs if Microsoft Windows XP does not have the Microsoft .NET Framework Version 2.0 installed. The .NET Framework 2.0 must be installed to prevent the error from reoccurring.
