Peter Martin :
why not windows 10 that has all the drivers in it? better os in every respect as well. hp doesn't even have win7 drivers. and if you can, use a 64 bit os
your HP came with Win10 preinstalled for crying out loud. 64 bit, so just install win10 and it will activate automatically for you as your license for win10 is built into the laptop
The 15-D009TU came with a Pentium N3510 from 2014? Almost certainly didn't ship with Windows10.
8/8.1, probably.
Drivers do exist for W10, but drivers are also provided for W7. With 2GB DDR3, I can't imagine either OS is going to be the best experience, but W10 (at least theoretically) has a smaller footprint & should run a little better....
jaslion :
I recommend you run a version of linux if you want smooth webbrowsing and whatnot.
A laptop of that caliber will almost certainly run a little better on a lightweight Linux distro.
The problem is, it's added complexity is not for everyone.
Peter Martin :
LOL, that is absurd advice! clean install windows 10 on that box like it came with
It's not necessarily an absurd suggestion. A little premature though, as a clean W10 install should be sufficient.
The 2GB of RAM and 5400rpm drive isn't going to do the system any favours though.
