Issue with Double-Click To Open

post #1 of 4
Thread Starter 
Here's the situation.

I am on a computer for which the Win7 desktop etc have the one-click behavior even when I *set* the double-click behavior. And now it's greyed out.



And here is a partial screenshot of the desktop to show what I mean. (though the "finger pointer" is absent)



Suggestions?

Plenty of times. What registry key will fix this?

    There are two registry keys that can cause the single-click option to be grayed out:
  • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

    Go to both of those keys in turn, and if you find a value named "ClassicShell", delete it (or set it to 0).  That should re-enable your ability to switch between single-clicking and double-clicking.

    The single-click/double-click setting itself is stored in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ShellState.  The fifth group of numbers in that binary value should read 13 for single-click, or 33 for double-click.

    The icon-underline setting is stored in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\IconUnderline.  If it doesn't exist, create a new DWORD with that name.  These are the possible values for it that I'm aware of:
  • 0: Always underline
  • 1: Never underline
  • 2: Underline when hovering only
  • 3: Follow Internet Explorer's setting

    You will have to restart Explorer (either with Task Manager, or by logging off and back on) for any of these changes to take effect.
