Thread: My cdrom icon is missing from "My Computer", exclamation mark in Device Manger

1) Go to "Start" then select "Run"

a) Type "regedit" and click "OK"

2) optional step
Backup you registry by:

a) Highlight "My Computer" by clicking on it once.

b) At the top of the page you should see "File"(Win XP) or "Registry" (Win 2000), click on this and then select "Export Registry File"

c) The following screen will allow you to select where you would like to save this backup and what file name you would like to save it as.

d) Please note at the bottom of the screen where it says export range "All"; this should be selected to ensure your entire registry is backed up completely.

e) Give the File a name and Click on the "SAVE" button (this will bring you back to the registry editor)

3) Remove the Upperfilters and Lowerfilters values by:

a) Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it.

b) Expand the "SYSTEM" Key

c) Expand the "CurrentControlSet" Key

d) Expand the "Control" Key

e) Expand the "Class" Key

f) Please look for a key containing the following string of letter and numbers:

{4D36E965-E325-11CE-BFC1-08002BE10318}.
g) High light this key by left clicking once on it

h) On the right hand side you are looking for "Upperfilters" and "Lowerfilters", once you find these please delete them by high lighting (left clicking on them once) and then right clicking on them and choosing "delete"

4) Restart your computer.

5) Your CD-ROM should be back.

Thank you for the valuable solution it worked .have a great day ....sashank

Hi,
That was cool answer ....hey but how did u manage to get it not shown in the MyComputer or the Explorer ......
If it happened accidentally then u could just have pushed the wires on the back of the ROM firmly and then restarted then also i guess it would have worked.

What say ?

It was indeed in my computer . i have tried tried restarting many times but with no sucesses until i followed your given procedure. Thanks once agiain

Thanks for a fantastic solution, worked brilliant.
Cheers.
