Third party programs that claim to be able to provide you with driver updates are usually just a way for someone to drain cash out of your wallet, or, worse, to update your drivers with ones containing malware.
As far as the upgrade to Windows 10 goes, in your case, if I were doing it, I would make a complete clone of whatever hard drive that you are using to contain the Windows operating system to another disk drive, and then disconnect all other drives and boot from the cloned Windows 8.1 drive and perform the upgrade to Windows 10, then test everything out to make sure that everything is working OK. The results of that test would determine how to proceed from there. If the Windows 10 upgrade is a failure, you have your original disk to go back to with Windows 8.1.
