HELP!!! Problem Created by 5.1 How to Print a Folder File List from Windows Explorer

Implementing this little feature has tied up my system.  I just want to know how to get my system back to normal, please!

1.  The next AM, after installing this,  access to the contents of my desktop folders is screwed up.

• the contents do not appear when I open these folders - instead I get an (apparently) empty folder with Windows Explorer search instead. (At first I thought a virus had wiped out the contents!)
• When I click on Folders, I get the complete desk top folders listing on the left.  Clicking on these left  folders brings up the contents in the window. 
• The files in the window are displayed without file extensions.
• The folders in the window do not behave properly.  Clicking on any of them just brings up another instance of Windows Explorer Search.  In order to get at the contents of the folders, I have to click on the folders in the listing on the left.
• If I open files from within an applications, everything is fine.  That's why I didn't notice the problem until the next AM.
• also, at first, the Start Menu did not work at all.  This has happened intermittently since, as I have tried to fix this problem.  Currently, it is working.

The files and shortcuts on the desktop are OK.  It is just the folders that are foobared. 

When I first rebooted, I got a message (approx) cannot close desktop proxy.  Searching on this problem brought the suggestion to untick- Windows Explorer >Tools > Folder Options > View > Launch folder windows in a separate process which seemed to fix that problem as this problem was related to the existence of multiple instances of Windows Explorer - which I could see in Task Manager.

I went back through what I did in case I made a mistake and there was one difference.  Here are the steps with the difference noted:

a) Open Notepad and then copy and paste the following text into Notepad:
@echo off
dir %1 /-p /o:gn > "%temp%\Listing"
start /w notepad /p "%temp%\Listing"
del "%temp%\Listing"
exit
b) Save the file as Prin.bat in the Windows directory, and then close Notepad.
c) Start Windows Explorer, click Tools, and then click Folder Options.
d) Click the File Types tab, and then click File Folder.

d1)Click Advanced (this step added by Gizmo)
e) Click Edit, and then click New. As Edit was disabled on my system, I just clicked New.
f) In the Action box, type Print Directory Listing.
g) In Application used to perform action, click Prin.bat, and then click OK.
h) Click OK, click Apply, and then click OK.

I don't have many folders on my desktop and they contained mostly shortcuts, arranged for my convenience.  I didn't know how convenient until this screw up, LOL! 

I went back to Windows Explorer>Tools>Folder Options>File Types>Advanced and tried Set Default (see below).  I got the Start Menu functionality back the file folders still do not function properly.

Here is what I currently have set:

Windows Explorer>Tools>Folder Options>File Types>Folder>Advanced
explore
FreeZip Help
open
PrintFolder
TreeSize
Zip

Windows Explorer>Tools>Folder Options>File Types>File Folder>Advanced
find
Print Directory Listing

The items in bold are there because I highlighted them and clicked Set Default in an attempt to fix the problem.  I also tried clicking Restore Defaults in both places with no difference except I get icons instead of my usual list display.

I thought that, perhaps, deleting this new Print Directory Listing thing would help but my edit and delete buttons are disabled.

Clearly, I have no business fooling around with this stuff as I only know enough to be dangerous.  However, I have never gone wrong with Gizmo's tips before.

I sure hope someone can help me get my system back to normal!

Thanks in advance for any/all help offered.
