Vista - Double clicking explorer always opens a new explorer window

This just started happening, perhaps in the last few days. I just want explorer to show the double clicked folder or drive in the same window, same as if I right click 'explore' on a folder item.

These are the things I've tried so far:

1) Control Panel -> Folder Options -> Open each folder in the same window
2) Uninstall all software installed in the last week (except nVidia driver and Internet Explorer 8 beta 2). Will uninstall these as soon as I can reboot.
3) Downloaded ShellExView (shexview) and disabled every explorer extension except 2 that are required to run explorer at all.
4) Ran Regedit and checked HKEY_CLASSES_ROOT\Directory\shell and HKEY_CLASSES_ROOT\Drive\shell for value other than 'none'

Please help if you can. A Google search shows a few people with the same issue but no working solutions.

Have you see this tutorial, and tried having the navigation pane on or off:

Open a Folder in the Same or Separate New Window

Hi, I had the same problem and I resolved following these steps:

- copy the values data of
COMPUTER\HKEY_CLASSES_ROOT\Folder\shell\open\comma nd : (Default) and
DelegateExecute to

COMPUTER\HKEY_CLASSES_ROOT\Folder\shell\explore\co mmand respectively
but delete the word /separate from de default value and, in case,
DelegateExecute does not exists create and paste the value of
DelegateExecute from the Open Key.


At the end, You will have the following value in the key
COMPUTER\HKEY_CLASSES_ROOT\Folder\shell\explore\co mmand :

(Default) -> "%SystemRoot%\Explorer.exe /idlist,%I,%L" .

DelegateExecute -> value of
"COMPUTER\HKEY_CLASSES_ROOT\Folder\shell\explore\c
ommand\DelegateExecute"

After that, the parameter works ok, means, if you select open each
folder in the same window or open in its own windows, works as should
be.

I got this from
<http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/Windows_Vista/Q_24375131.html>
and it worked. Double-clicking folders in explorer will now open in the
same window.

**********************************************************
* open a new "Command Prompt" window by right-clicking and selecting
"Run
as administrator";
* at the prompt, run the command "regsvr32 actxprxy.dll".
