Hi all,

New build, installed Win7 (DVD ROM), download/install Win10 - works great, but now the ROM drive doesn't work after installing 10 as it did to install 7 from drive. The drive appears nowhere in the computer, not even in "Disk Management". However, following the path of:

Control Panel, Administrative Tools, System Information, Software Environment, System drivers - scroll to entries cdfs & cdrom.

These lists as:



Description: CD/DVD System File Reader

File: C:\windows\system32\drivers\cdfs.sys

Type: File System driver

Started: No

Start Mode: Disabled

State: Stopped

Status: OK




Description: CD-ROM Driver

File: C:\windows\system32\drivers\cdrom.sys

Type: Kernel driver

Started: No

Start Mode: System

State: Stopped

Status: OK



Please note the cdfs entry under Start Mode; as the hardware exists and is known to work and the drivers are installed (but disabled), I am left with the only logical conclusion that Microsoft, in it's oh so benevolent Big Brother's 'wisdom', must have determined that I no longer have a need for an optical drive. But it's my toy and I want to play with it.

Now I'm no coder, I just push the trons, but it seems to me that this is just a bit in the registry somewhere. So my question is;


Where do I go to FLIP THIS THING OFF!


Thanks, folks

 Hi tronpusher and welcome to our forums

, :welcome:


This does seem to happen to a lot of folks.... :(


There are a number of possible solutions, but it can be a trifle time consuming in getting the DVD/cd recognised

Take a look here:



It should work Ok on win 10
