My CD/DVD drive L is recognized by the computer under Windows 10 (upgraded). It will read/write CDs but not DVDs. Device Manager shows no problems and I have uninstalled the device then scanned for hardware changes, region/country is set to 1. Troubleshooters show no problems. Rarely used the device so I don't know when the problem started. I have always used DVD+RW in the past with no problems.
I once had the same symptoms, " It will read/write CDs but not DVDs", when the drive's lens became dirty. I managed to clean it using some DVD lens cleaner fluid [it was some sort of alcohol, possibly isopropanol, and was the same as that I had had for ages as magnetic tape head cleaning fluid].
I managed to clean the lens half a dozen times over the course of a couple of years but it eventually failed completely after, I think, I had got a bit heavy handed and allowed some of the fluid to get into the electronics rather than just the lens itself.

I assume this is a standard Desktop Optical drive. There is too much disassembly to bother with cleaning the lens, personally I won't use cleaning discs. Just buy a new one £12(10 USD) from my UK supplier.
If it's a slimline laptop type drive where the lens/optics comes out on the disc tray those are easy to clean if you are very careful. They cost a bit more to replace but are still cheap.
Problem solved, went out and bought another drive, cheaper than wasting time trying to fix. I saw a number of reports of people having problems with their DVD drives after upgrading to Windows 10.
