Cleaning up computer that has really slowed down. Now getting this error message. How can I find out what's causing it?

When exactly does this happen ?

Was happening constantly. Finally figured out it was probably caused by Adobe searching for updates. Purged my start programs and put in only the ones I need. Think I got it right; at least the message has disappeared.

Thanks.

Does the number of items I have in taskbars on my screen affect overall speed?

Have run Ad-Aware, ClamWin, AVG, CCleaner and Eusing Free Registry Cleaner. Have defragged drives.

By taskbar you mean tray (right part of the taskbar) ?

The more app in the tray, the more app need to be ran at boot + the more app using CPU and memory. So yeah, this slow down more or less the system !

Most of app that appear in the tray can be deactivated in their option (look for "start automatically with windows" or "autostart" and uncheck it).

For remaining process, I suggest you "regcleaner", or other app that allows to clean the startup apps.

No, user taskbars, like on side of screen.

I have used Eusing Free Registry Cleaner to remove everything from the startup folder and replaced with the couple ones I need (virus, firewall). It's a pretty nice freeby.

In the "Quick launch" so. Its just a toolbar and the icons are just short links. You can have has much as you want. I even use to set my taskbar on 2 rows, with the "Quick Launch" on the first and the task running on the second. My quick launch has currently 36 icons.

I'm at 101 with tool bars on left, top. right.

Thanks.
