Deleted Registry Entries in an Attempt to Repair CD-Rom Drive

[JuiceCULT]

My situation: My CD/DVD-Rom drive is unresponsive (it opens and closes normally) and does not show up on Device Manager.

I read a guide that suggested that I have corrupted registry entries.
It told me to delete UpperFilters and LowerFilters.
I deleted the two entries (and possibly others in the same location).

Good news: I backed up my registry
Bad news: I backed up my ENTIRE registry (oops)

So far, everything appears to be the same... Except when I open iTunes I get an notice that says the registry settings needed to burn and import CDs are missing.

I've been told that I can import the entire .reg backup and "hope that all goes well". It sounds rather sketchy and I am seeking better help. It would be well appreciated if someone were to give me a tip.

Note: I've also been told that a wire could have come loose but I want to fix this registry problem before opening up my PC.
I hope it doesn't come off as leaching by coming here solely for making a help thread. If someone can guide me I'll try to help people in return. Thanks.

Was that the only problem that you were experiencing when you backed up your registry?
How did you backup your registry?
If it was with a System Restore point, then that's the best and easiest way to restore it. Just run System Restore and go back to that point. At work I routinely delete registry entries and often delete things that I shouldn't (in search of a fix) - but System Restore (in Win7) has saved my bacon on several occasions.

Yes, the only problem at the time was Windows not recognizing the CD-rom drive.
I exported the data using regedit.exe and set the export range to 'all'.
I don't have a restore point made prior to the deletion.
Would there be any risk in importing the .reg backup file?

None that I know of.
Set a restore point first - "just in case"
Make a System Repair Disc (Start...All Programs...Maintenance...Create a System Repair Disc) You can use that to access System Restore in case things don't work as expected.

Unfortunately, I did try to merge/import the .reg file and it didn't work.
At first, there was an error saying that not all of it was successfully imported because they are in use or something
Then I tried to import in safe mode and it said it was unable to access the registry.
I ran as administrator and changed all permissions and still got the message.
The sound on my PC was shut off after rebooting so I had to go back into safe mode and use the restore point I created.
Still, the drivers are missing and I'm pretty sure that .reg backup isn't corrupted at all.
Any ideas?
