i was having the same issue with the same cddvdw drive. i found the stuff you guys posted in these forums BUT i also found a much more in depth set of step by steps. heres the link: (still good as of today)
After upgrading from Windows 7 Home Premium to Windows 10. My HP CDDVDW TS-U633J Device (DVD) does not show in my device manager. I am trying to find Windows 10 driver for HP CDDVDW TS u633J Device. I have Windows 10 Version 1909.
Since my Device Manager was not even detecting a CD/DVD Device, nor did it have a CD/DVD Device Category, the only way I found out was I went to Backup Restore and it told me the hp CDDVDW TS-U633J was disconnected.
Thank you for taking the time to research my problem. I understand that HP will not create Windows 10 drivers for my particular laptop. My laptop is an I5 Intel processor, with plenty of ram and processor speed to handle Windows 10. Microsoft is no longer supporting Windows 7 as of January 14, 2020. Though I loved Windows 7 Home Premium, I did not want to be in a situation where my laptop will be vulnerable to increased security issues. I decided to upgrade to Windows 10. It works fine accept my DVD Drive is now not functional. I will continue to use this laptop without the drive. I can do without the DVD Drive.
