Thank you for the inquiry.
I cannot assure if drivers for 64-bit drivers are going to be release or not.
32-bit based OS is the one Intel® considered is the best regarding performance for the unit, so far, you could check every once in a while in the download center to look for driver releases (https://downloadcenter.intel.com/ Drivers & Software)
There is an option.
It would be to check the HW ID's of those devices.
Here how you can check that:
1. Access device manager and find the unknown devices.
2. Right click and properties.
3. Go to "Details" tab
4. Change Property From Device Description to Hardware ID's
5. Copy those codes and google them
Regularly, when you do this, you are referred to a website related to an specific component of the computer, which can better advise you on the drivers to look for.
Hope this helps, any additional questions please let us know.
