Whenever you install programs they tend to add a program to your Startup folder, which allows the program to start immediately when Windows starts. This can greatly affect the performance of your system and even cause some instability. Some startup programs can even prevent other programs from installing or starting properly.
How to Remove Programs from Startup
Click Start, type: msconfig
Hit Enter on your keyboard. This will open the Microsoft Configuration Utility
Go to the Startup tab. There you will see a list of checked that set to start and load with Windows. You can see I have quite a few checked, some might be important, it’s up to you to carefully decide what you believe is not essential and what might be slowing down the system.
My recommendation includes avoiding your Antivirus utility, audio programs such as Kmaestro or Sound Blaster. Some of the common ones I like to disable include, iTunes, Quicktime, WinAmp, Adobe Acrobat, Windows Live Family Safety.

Once you have identified the programs you don’t want to start with the system, uncheck them then click Apply and OK.
You can choose to Restart now or Restart later if you want.
