It's more the 'HP' part of the original post that I'd be worried about. Notorious for fan(s) overheating and causing the left hand hinge to come away from the main casing. Dump the HP branded stuff (advisor/dock/updater) asap.
I used Windows7 for long enough and steadfastly refused to upgrade even to Windows8.
After seeing 8 run on my son's laptop I decided to take the leap to 10. Yeah initially it was frustrating with the continual updating and a system/desktop I just wasn't familiar with.
Works fine for me now and is nowhere near as heavy on CPU as previous versions.
Plenty of info online regarding what's safe to turn off/delete etc. e.g. I've no interest whatsoever in the 'X-Box' apps.
@ the OP; just remember if you do purchase a Windows10 OS you may well
find your laptop, since leaving the factory originally, is months
behind regarding further updates.
Hope things work out for ya.
