Stopping a Data CD From Auto launching

Solution #1:

1. Right-click on the My Computer icon, and select Properties.
2. Choose the Device Manager tab.
3. Open the CD-ROM branch, and select the entry for your CD-ROM drive.
4. Click Properties, and then choose the Settings tab.
5. Turn off the Auto insert notification option.
6. Click OK, and then OK again. You'll have to restart Windows for this change to take effect.

Solution #2:

If you hold down the Shift key when inserting the CD, the autorun is bypassed. (although it's not exactly graceful trying to insert a CD while holding down keys on the keyboard.)

Warning: Always Backup your registry before makeing changes!

Solution #3:

1. Run the Registry Editor (REGEDIT.EXE).
2. Open HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer.
3. Change the Value of NoDriveTypeAutoRun from 95 00 00 00 to BD 00 00 00.
4. You might have to restart Windows for this change to take effect.
