I let Windows 10 handle it, using generic drivers where needed and they worked fine. I tried updating drivers but don't remember what did or did not work. This was 5 or 6 years ago, sorry.
I currently have a HP Pavilion DV7-6C63NR laptop which also has no Windows 10 drivers, only Win 7 and 8. It runs amazingly well, especially with 8GB Win 10 Pro X64 or RAM and a 500GB SSD. Currently running 1909 18363.562. Device Manager has no yellow or red marks, everything is working. Sound card is running a generic driver and works fine.
Edit: The first thing you need to do is backup your current install. The best way to do this is to use Macrium Reflect Free to make an image backup to an external hard drive. If you don't have an external hard drive now is a good time to get one as regular backup should be a part of your normal process. You can get a 1TB external hard drive for $60 (less if on sale).
Then do the upgrade to Windows 10. If any serious problems (doubtfull) recovery is 20 to 30 minutes away.
