I've gone back over the program you recommended above (the one recommended yesterday, the name escapes me now) and there are STILL the non-existent references!
And Registry Mechanic, which I run every day, and have run every day for a long time, shows that there are 15 registry entries set for deletion, the ones that I tried to delete with CCleaner and the other program. However, even though Registry Mechanic shows them to be fixed, they are NOT!!!!!!!!
I have run Registry Mechanic several times and rebooted after each time to no avail.
I will try Startup Inspector. I don't want to use a registry editor because I am NOT an expert. I may have to find one to fix this problem. I do believe that these extra non-existent entries are slowing down the system...I have too many things in the tray, for example.
Ok, off to try Startup Inspector...thanks!
