I very recently installed Windows 7 on my desktop computer and I'm loving it so far.

One of the major things that bugged me though was the new Explorer behavior. The automatic folder type discovery just goes ahead and tries to determine a folder type just by looking at how many (or if there are) files of a certain type (pictures, videos, songs, ...) are in the current folder, and then it adjusts the viewing settings accordingly. For example, if you open a folder that contains mainly video files, it would show those with big icons instead of my default, a detailed list. Pictures are displayed as thumbnails.

Disabling this behavior proved to be interestingly difficult. As with most things that have been declared a default setting by Microsoft, it luckily can be done - but only via registry.

First we need to delete our current folder type settings.

• Close all open Explorer windows.
• Open the registry editor with Start => Run => regedit and browse to HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell.
• Delete and confirm the deletion of the keys BagMRU and Bags.
• Now create a Key (right-click on the current key in the left pane and select New => Key) called Bags.
• Create a subkey for Bags called AllFolders.
• Create a subkey for AllFolders called Shell.
• Create a String value (right-click in the right pane and select New => String Value) called FolderType and set the value to NotSpecified.
• That's it for Windows 7. Please read the note for Windows Vista x64 below. Otherwise, just reboot and your new settings should be applied.

That's it for Windows 7. If you're using Windows Vista x64, it might be possible that there is a copy of (or a similar) the Local Settings\Software\Microsoft\Windows\Shell key in HKEY_CURRENT_USER\Software\Classes\Wow6432Node. I could not confirm this for Windows 7, though I am using the 64 bit version (it just had a CLSID subkey, nothing more). In that case, delete the Shell\Bags and Shell\BagMRU folders like I told you above before finishing your modifications with a reboot.

Warning: as always, playing around with the Windows registry can be dangerous when done incorrectly. If you do not feel safe about it, make sure to back up the keys you're about to modify via File => Export, or leave it altogether. I do not take any responsibility for any damage, nor do I give any guarantee that the steps I provided here will work for you. At least they worked for me.

Hopefully that was of help to you

I discovered the initial instructions on mydigitallife.info. Thank's so much Had a hard time finding a guide for that.
