Usually, you don't have to do anything. Windows 10 has built-in drivers for most of these older components. If not, you will need to check the website of the manufacturer for your wifi/bluetooth module for an updated driver. If this is an Intel wifi/bluetooth module, Windows 10 drivers are definitely available; do a search at http://downloadcenter.intel.com and you should be able to find them.
Thank you for joining the Intel communities.
In this case, you can try to upgrade to Windows 10 but please be aware that there is no drivers available for this motherboard using Windows 10 so you can use it but it will not be as good as you hope.
Now, try to see if you can update Windows with all the updates available and then try to see if you can upgrade to Windows 10.
