Windows XP doesn't recognize your computer's DVD-ROM or CD-ROM?

Some times after installing Microsoft Windows XP, it doesn't recognize your DVD-ROM or CD-ROM. To resolve this problem do following;
1- Click Start Menu > Run > type "regedit" and press OK to open Windows Registry Editor.
2- Go to following Address:
3- In Registry menu select "Export Registry File" to make a Backup from your registry entry.
4- If there is "UpperFilters" or " LowerFilters" keys, delete them.
5- Close Windows Registry Editor and reset your Computer.
6- Go to Control Panel > click System > go to HardWare tab and click on Device Manager button.
7- In Device Manager list, click on Device marked with "?" , from Action Menu select Uninstall and press ok to uninstall device.
8- From Action menu select "Scan for hardware changes" to Scan your system and install DVD-ROM or CD-ROM.

Thanks. Success reinstall. But my regedit key is {4D36E965-E325-11CE-BFC1-08002BE10318}

That could be because that key is a GUID (Globally Unique IDentifier), and that different versions of Windows generate that GUID in a different manner. Registry value (Default) for every key in Class should specify the class name. I use Windows XP Professional, Service Pack 2, and have the same GUID/regedit key as you.

That happened to me. I just returned my laptop and got a new one haha. Funny thing was, though...The new one was faulty aswell, with a different problem...Then I got this one and the volume scroll thingy doesn't work lol.

I guess that's what you get for being cheap.

You should never have to do this hack if you install windows correctly. As in, you do a full system format with an install. You might get this if you do a repair install or an upgrade because it does not fully erase your registry, etc. This is why a clean install is always recommended. Not only will it increase performance of your computer because the registry is clean, but it also will fix tons of issues that your system has that you do not know about. This is also the reason why a clean install is recommended to be done every 6 months to a year. Even with a good registry cleaner, etc. it is still recommended you do this. I know it can be pain but if you do it a few times you get a system going. It takes me maybe 1 day of installing stuff to be fully back to my system if that long. Plus, most of that time is my computer doing work and not me.
