I'm too OCD to be able to do it any other way.
Josh does it take long to boot meaning the time from seeing windows logo to being in the windows ?
It might be worth running cc cleaner and malwarebytes ? just to be safe...
Also it can be a program that is trying to start and fails, maybe Event viewer can tell you if there is something failing ?
Also windows button>msconfig>startup what do you have there ?
Trying a clean boot is also an option....
Clean boot
I have reinstalled windows after 4 years and that's only because I have changed 90% of my hardware so it deserved a nice clean start but otherwise reinstalling is my last resort cos as you said windows only takes half an hour but the drivers, programs, and bf4 whopping 40 gb...takes ages.
Nuke it from orbit it's the only way to be sure!
You can tell this bolke works in IT
