Speed Up Your Computer With A Registry Change

In my last post, I talked about one way in which you can speed up computer performance by disabling the User Account Control warning messages found in Windows Vista and Windows XP. The change to the registry setting doesn’t speed up the processor in any way, but instead eliminates delays and interruptions. On the negative side, disabling the messages leaves you open to engaging in actions that are possibly dangerous to your computer.

Today, I have another registry change that will speed up your computer by eliminating a delay. Once again, I don’t advocate editing the registry if you’re a complete novice when it comes to using a computer. Editing the registry is highly effective at changing the behavior of your computer, but it makes the changes you ask for immediately, and there’s no way to “undo” what you’ve done short of restoring an unchanged copy of your registry.

I’ll again recommend that you back up your registry before you make any changes of any kind. RegCure creates a registry backup each time it operates and before it makes any changes to the computer. It will also restore registry backups if a change puts your computer into a bind.

Today’s registry edit will disable the autoplay feature that is turned on by default for CDs and DVDs that are inserted into the drive. In some cases, this feature is useful, but you may find that reading and playing a disc takes an unacceptably long time, especially if you don’t really want the disc to start playing in the first place!

This particular registry change won’t affect your ability to play discs you’ve inse rted. You’ll just have to start the discs manually. To disable the autoplay feature:

Start RegEdit
Within RegEdit, find:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\Explorer
Right-click New, then Key. Name the new key NoDriveTypeAutoRun. Press Enter. Right click the key you just created and select New/DWORD Value.
Enter a name for the DWORD Value and press enter.
Double-click the DWORD to open the Edit DWORD Value dialog box. Enter 000000FF into the DWORD Value box. Click OK and then close RegEdit. This change will take effect when the computer is restarted.

The computer will not autoplay discs that have been inserted in the drive. You’ll need to manually start each disc. To return to the default behavior (autoplay), use RegEdit to remove the registry key.
