Reduce the number of programs running at startup If your PC is taking too long to boot and it runs slowly afterwards, it’s probably because you have far too many programs running at startup. Reducing this is easy, it will make your PC launch noticeably faster and lighter upon first load.
To change the items running at startup, go to Run using the hotkey Windows key + R, and type “msconfig.” A small window will appear (see the screenshot above), select the Startup tab. From here you will be able to turn off many startup programs, which can shave several seconds (or minutes) off your boot time. (Note Windows 8 has moved this functionality to the Task Manager). Try to make sure you research what you are turning off as some processes might be needed by third party programs or drivers you have installed.
Reduce Slugishness To maintain reasonable speeds of your PC go to Services Tab and check ‘Hide all Microsoft Services’ and then hunt for services that you do not need, again make sure you have researched well about a service and what the PC uses it for.
