Great now do this: Start CCleaner again and this time click the Registry button on the left, then click "Scan for issues" when its done click at the bottom "Fix Selected Issues, then select Fix All. That will get rid of a lot of trash and uninstall exe files that are no longer needed. It will remove old Active X Entries. Do that then reboot your computer. You're doing great I'm glad you are taking my advice, your computer will thank you for it. :)

WELL What a lot of issues, I did as you said.

Lots of missing shared DLL

Unused File Extentions

Many of invalid default Icons

Active X/COM Issues

Installer Reference and others.

I did not backup changes to Registry

Broadband Medic came up fleetingly after I re-booted.

Good. do that every few days and you should be alright. Want to go to stage two? I'm willing to help if you want to take it to another level, and perhaps fix your task bar situation. I have some ideas.

I am always willing to learn

But now it is late so I will learn more perhaps to-morrow.

Thank you very much.

Ok that's enough for one day. You did great.

Here is stage two for you that I recommend: Download this free program version called malwarebytes:

Download it, and then Install it and run a full scan. Its a great program and I have it too. This program has potential to find things Spybot can't or doesn't look for, and maybe fix your task bar situation. Like I mentioned before it could be a program running on your computer making that problem happen, I suspect it might be malware. This program is about finding malware on your computer and removing it. I'm not saying this is a fix for your task bar problem, but it certainly can't hurt to run the program and see if it finds anything. Keep the program even if it doesn't, you may want to run it every now and then if problems arise on your computer. Its free and easy to use, and powerful. I highly recommend it.
