I was searching everywhere for this on search engines, and I couldn't find the answer anywhere, at least not directly. Appearently people don't tend to know this, and it may or may not be needed regularly.
I wanted to know it, because I'm learning that I can automate things by customizing the Files and Settings Transfer Wizard, and I'm adding that key as one of the saved options, for convienience to me. But it took a long time to find. Here is where I finally, found the answer:
http://www.msfn.org/board/lofiversio...hp/t74418.html, which has a link to here:
http://www.msfn.org/board/Large-Icon...ic-t38289.html.
Now I'll tell it directly. The key is found here, and it is switched as shown here:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\WebVie w\BarricadedFolders
* shell:ControlPanelFolder (REG_DWORD)
* 1 is Category View
* 0 is Classic View
I found it now, and it's very useful to me for what I wanted. I'm posting it here now, for the benifit of others who may be also looking for the same thing, even if for a different reason.
