Laptops tend to be slow because they have slow hard drives (5400rpm). And, if you dont tweek your laptop it is going to be slow. So, a few tips:
1. disable automatic updates (set them to manual with notifications to update)
2. disable auto defragmentation
3. when you install alot of programs system restore kicks in and slows your HDD even more (disable system restore (if you are confident) and enable it after you installed everything and create a restore point then.
4. antivirus software should be installed last (if you install /known/common safe programs)
5. google "autoruns for windows", download the program, run it as administrator(after installing everything) and disable whatever program you dont want to start @ windows boot (be carefull not to disable any driver or something else, just disable programs that you dont want to autostart)
