We don’t need many programs at startup like Adobe reader, Adobe update, winzip, Google update etc. These programs should be removed from windows startup to improve windows 7 performance.
Personally I would enable only Antivirus, Firewall, Sound and graphics at startup.
In this post, I will show you how to add, remove, enable, disable a startup program in Windows 7.
Start >> All Programs >> Right click Startup folder >> Open
Start >> All Programs >> Right click Startup folder >> Open all users

To remove any program from start up, just delete that program shortcut from the folder. To add a program in startup, create a shortcut of that program in that folder.
Start >> type msconfig in search box >> Press enter

Click “Startup” tab. Uncheck the program you want to disable from startup. Check the program that you want to enable at startup.

Click “Apply” button. Now Click Boot tab and check “Make all boot settings permanent” box.

Now again click “Apply” button, Windows will show a warning message.

Click “Yes”. Now Windows will ask you to restart system. Click “Restart” button. Now your windows will restart.
Done!!
You can also enable disable, add or remove startup programs using some third party free software.
