You don't seem to know that Win7 is driver-complete in the installer and then via optional Windows Updates. Only one or two drivers may be missing after that which are easily found on the model's Support Downloads webpage.
The corruption from bloatware is insidious and does not end when you stop the crap from running at startup. The only way to get clean is to do the reinstall. Until then you don't even have Win7 but a ruined version of it. Of course, we are purists here at its home.
You mention it several times so have you tried a Repair Install?
I would run at least one bootable AV like Bitdefender or Kapersky first. These will clear you for Repair Install since going through it on an infected system is likely fatal.
But if you're going to reinstall the OS as a Repair INstall does, you might as well do the perfect reinstall. Why argue with having the proven best vs. having the absolute worst?
