6) Click on OK.
7) You will then be asked to restart your computer, which is not necessary. So, you can click on 'Exit without Restart'.
8) When you start the OS (Operating System) again after following the above steps, a window of an msconfig message will appear. Check the option given above the OK button & click on OK.
Some programs get ticked again even if you untick it. For such programs, you can mention to them not to start on Startup by changing the settings/preferences in the program. Also, if you wish to load only the basic applications on Startup (to minimize the Startup time), follow the above steps till Step 3. Then, select the Diagnostic Startup & click on OK & then follow the 7th & 8th steps.
