Keep in mind your laptop came likely with tons of free applications and they are taking valuable space and using valuable resources. Go to msconfig and then to start up and you'll see all the applications that open and await your next command even if you don't ever intend to open them. So the first step is read here some excellent free advice and get slowly familiar with it all!
Understand there are no hard fast rules here for what you should always allow to start up.
I like my Antivirus, Logitech setpoint and Acronis schedule to start up. Keep in mind by disabling all you can always start your programs as you want, they just won't automatically be waiting for you to issue a command or retrieve updates or perform features within them till you open them.
Another thing to note by "disabling all" in msconfig, windows always reassigns what it will need to boot. But for sure have your AV program checked to open so it will automatically grab updates and work while you surf and such.
