If your computer is visibly slower with each successive start, then programs that have added themselves to the “Startup” menu might be the source of the problem. Windows 7 includes an option for you to selectively enable and disable these items.
Step 1 – Click the “Start” button at the lower-left corner of your screen. The window that pops up is referred to as the “Start” menu.
Step 2 – Type “msconfig” into the search field at the bottom of the “Start” menu, then press “Enter” on your keyboard.
Step 3 – Click the “Startup” tab at the top of the window.
Step 4 – Scroll through the list of startup programs, then click the box to the left of each program that you want to enable. To disable programs, click that same box to remove the check mark.
Step 5 – Click “Apply,” then click “OK.”
Step 6 – Click “Restart” to restart your computer and begin the startup process with only the programs that you have specified.
