I have recently discovered that cdrom.sys has been corrupted on my Windows 7 computer. I tried to repair it using Windows 7 CD but it didn't worked. It says my Windows installation is flawless. I tried to some download file for the same but didn't find any. Can you help me?

Is it a fresh installation of Windows 7 or an upgrade from Vista? This might be one of the reason of cdrom.sys got corrupted. Downloading a new file of it will not work in your case. So I recommend to perform a clean install of Windows.

But why do you want this cdrom.sys file. Windows 7 has its own CDRom drivers. So there is no requirement of this if you are running cd/dvd on your Windows computer. The cdrom.sys file is only used when you use your CD ROM drive in DOS mode. But if you are not using your CD ROM much on DOS mode then its absolutely fine. You won't be having any problem while running Windows.
