Issue with folders opening new windows

[cooker3]

I just installed windows 7 this week on my dell xps.
But an issue occurred friday which I can't fix.
When I try to open a new folder it always open in a new window. I have "Open each folder in same window" clicked.
I have googled and tried a myriad of different ways which people would say work but for me it hasn't

If I right click and choose open it will open in same window but not if I double click. It's rather annoying as you get tons of folders very quickly.

Anyone have any ideas for how to fix it?

Hi cooker3,

Copy and paste the following code into Notepad. Click on the File menu, then Save As and click on the drop down menu to change the file type to All Files. Save as fix2.reg to your desktop:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\shell]
@="none"

Double click the file to run it, accept the changes to the registry and then reboot.

I always like to backup the registry or set a new Restore Point before doing anything with the registry.

Let me know if any of that helps.

Thanks for the reply. I had tried that but it didn't work.
Thankfully I came across the answer on another forum. I'll post it in case someone searches in future

Try running a system file check and then register the mentioned .dll:
The System File Checker tool:
To determine whether the issue that you are experiencing is caused by one or more system files that are used by Windows Vista, run the System File Checker tool. The System File Checker tool scans system files and replaces incorrect versions of the system files by using the correct versions.

To run the System File Checker tool, follow these steps:
Click Start -> click All Programs -> click Accessories -> right-click Command Prompt , select Run as administrator . If you are prompted for an administrator password or confirmation, type your password or click Continue .
At the command prompt, type the following command, and then press ENTER:
sfc /scannow
When the scan is complete, type the following command, and then press ENTER:
regsvr32.exe /u actxprxy.dll
