How to Stop programs from making your computer run slow at startup.
Every time you startup your computer there are always a few unnecessary programs starting up in the background. This slows the boot process down. There are two ways to control which application launches at startup. One way is to use a program like Tweak UI, or you can change it manually yourself. Here's how
Click the Start button (left bottom of screen) or the windows key on your keyboard.
Then choose the Run.
In the text box type msconfig.
Then choose the Startup TAB.
Simply un-check the ones you would like to disable.
Then Press Apply and then ok.
It will ask you to re-boot your computer.
When you restart it a window comes up that says you have chosen Selective Startup. Just Tick the box, Do not show this window again and then click ok.
