window vista doesnt recognize dvd/cd

1. Click on START button, the click on RUN.

2. Enter REGEDIT and press Enter.

3. When REGEDIT starts, open up the following key:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/
{4D36E965-E325 -11CE-BFC1-08002BE10318}.

4. After clicking on {4D36E965-E325 -11CE-BFC1-08002BE10318} you should see two settings on the right-hand side:
"Upperfilters"
"Lowerfilters"
Click on each of them, press DELETE and click YES.

If ^^ doesn't help, run this Fixit scan.

I have the same problem with Vista. It was alright when I first reformat and load Vista. But when it update, I lost connection with my dvd/cd hardware. Ihad enough with Vista. I reformat it again and use Windows XP much more reliable than any other Windows. Tried and true XP/
