You should also check with the PC manufacturer to see if there are updated drivers for the motherboard's chipset, storage controllers, network adapters, display adapters, and other important hardware devices. That's especially true on a PC that was designed before the release of Windows 10 in 2015.

If you encounter a compatibility block, the first thing to do is check for a BIOS or firmware update.
