How to launch Regedit for CD-ROM

Hello,
I have a concern with the Operating my CD-ROM drive. It starts (noise) but the CD does not open. The icon of the CD changer (cd audio) but does not recognize the cd-rom. I do not know if this is related but I'd rather say Some time ago I cleaned my pc with another forum but changed my handling regedit and I can not run since.
Finally when do start/ run / regedit nothing happens except that my mouse is coupled with an hourglass that persists until the expiry of the PC And when I look at the manager / process, regeedit constantly switched on and off without ever stabilize.
Here I hope I was clear.
Thank you :rolleyes:

Hi,

first check your system with any one of the Good Anti-virus software, whether your system is been affected by any virus.
Check the drivers of your CD-ROM drive whether they are working properly.

Which Computer are you using? is it Laptop or Desktop? That will be necessary to understand first because any play with the registry may cause the PC.
