If you are looking to delete unused programs, simply go to:Start > Control Panel > Add/Remove Programs
If you wish to remove shortcuts from your desktop, simply right click
on the shortcut and choose Delete
If you want to stop a program from Autostarting eveytime you start up your computer, go to:Start > Run
" (without the quotes) Click OK
Click on the Startup
tab. Here you will find a list of programs that start when you boot your computer. Uncheck any you don't want to start when you boot up. (You still will be able to start programs through their shortcuts or by going to Start > All Programs
. Unchecked programs just won't start automatically at bootup and won't be running in the background.)
You can Google entries or use the Bleeping Computer Startup Database HERE
to research the various startup entries, as sometimes they can be a bit cryptic.
Your processor may jump to 50% usage when it is busy doing a task, this is normal. Once your programs are up and running the computer is 'quiet', your processor should be at a low number, perhaps between 1 and 10%. This is normal. If it is stuck at a high number, then you have a problem, perhaps with a corrupt program that is running.
In fact, it is not uncommon to see a processor go to 100% once in a while, it is just not normal for it to stay there.
