why is CCleaner so great?

My cd/dvd was erased after I downloaded CCleaner. I used it and it was supposed to be safe. Now I can't use my dvd/cd drives. I read on other forum answers that I can fix it somehow, but it was very confusing and said that I need to uninstall other programs that used cd/dvd and I did not have a clue which programs did that. I think I have at least 5 kinds of programs like that. I don't know. Anyway, also, it gave such a long drawn out solution, I had no idea what to do next and it didn't explain anything at all. I am just a stay at home mom that wanted to get the junk off the computer.

Did you lose your cd drive after a file or reg cleanup?

If it was a reg cleanup can you restore from the backup if made or maybe try a system restore to before the prob?

Also check in services that the "Shell Hardware Detection" service is set to auto and has started.

Start - Run - Type services.msc
