　　Modifications to the optical drive problem

After the virtual optical drive is installed, one more CD-ROM drive will appear in My computer. Some users do not like others to use their own computer CD-ROM drive, now even worse. We can use the registry to modify the virtual out of the optical drive icon to remove, and then use a simple way to the original physical optical drive shielding, so that your optical drive is not easy to be used by others. In addition, the installation of virtual optical drive may also give friends who like to play disc games, so let's take a look at how to solve some of the problems caused by virtual optical drive.

Delete the virtual CD drive letter from My computer:

Opens the Hkey_local_machine\enum\scsi subkey branch, it will have two subkeys, respectively, corresponding to the physical optical drive and virtual CD-ROM keys, now the branch of the subkeys are all deleted, restart the computer, the physical optical drive back to be found, the system will fill out this subkey under the key, and the virtual CD-ROM drive letter is missing.

Prohibit the use of optical drives:

In addition to the hidden disk operator that we mentioned in the System appearance registry modification, if your optical drive is installed on the secondary IDE channel, you can also right-click [My Computer]| [Property]| [Hardware]| [Device Manager] to screen out the optical drive, open the plus sign before the IDE ATA/ATAPI, see the main IDE channels, secondary IDE channels, select the secondary IDE channel, right-click, select Deactivate, and click OK. A red fork appears on this option, and you can see that the CD ROM device that appears at the top is now missing, and the optical drive is not visible in my computer. And all you have to do is turn the secondary IDE channel back on, and right click on it to see and use the optical drive right away.

Disable the autorun features of the optical drive:

Perhaps your CD-ROM drive is not used frequently, and it can be inconvenient to automatically play the contents of the disc every time you insert it, by modifying the registry to prohibit this feature. Open Hkey_local_machine\system\currentcontrolset\services\cdrom Branch, the right window of the key value item "Autorun" data from the original 1 to 0 can be, restart effective.

Problems with virtual optical drives that are not recognized after installing virtual optical drives:

Some friends in order to avoid playing the game every time you need to insert the CD-ROM trouble, installed a virtual optical drive, can be a problem: when the click to perform "Establish VCD file", the system prompts "No physical drive installed on your machine", or "build VCD needs at least one physical CD drive ", that is, the physical optical drive is not recognized. The possible cause of this problem is that the allowed disk characters in the system are full.

Open Device Manager, look at the configuration of the CD ROM, found that only one optical drive identified, is the physical optical drive, the assigned letter is "G". Open the branch of the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup subkey in Registry Editor and look at the "lastdrive" key value under the branch, which is "G", Change it to "Z" and reboot the computer. The physical optical drive is not working properly because the virtual optical drive preempted the "G" letter, causing the physical CD drive to conflict with the letter. Similarly, there are many more partitions in the system, as well as the use of multiple physical optical drives.

When a virtual optical drive is installed, the disc game cannot run:

After the virtual optical drive is installed, the disk character of the physical optical drive is automatically moved backwards so that the previously installed disc version of the game will not function correctly and the system prompts you to "Make sure the disc is already in the CD drive" or "Insert Disc". Of course, you can uninstall the game and reinstall it. However, the simpler way is to modify the registry, open the HKEY_LOCAL_MACHINE\Software subkey branch, find the game name of the subkey, the layer by level, there will generally be a letter to install the CD-ROM key value items, the value of the change to the current physical letter.
