José,

Type in Start, Run:

regsvr32 /i shell32.dll

There are two possible reasons for this.

Hello,

I have Windows XP Pro and I recently downloaded some nice folder icons that
I wanted to test.

In the File Explorer I went to /Tools/Folder Options/File Types

There I changed either "File Folder" or "Folder". Thins is that, every time
I now click on
a folder in the file explorer a new window opens with the content...

How can I revert this to the default action?

Thanks for helping out

Regards,

/José Jeria
