Default view in windows explorer

[Guest JB]

I have read many of the articles and posts on how to change the default view

for windows explorer using the command line options. I have also seen the

info about updating the registry but all the ones I have seen talk about

updating HKCU. The issue I have is that the default has changed for all

users. I want to be able to set them all back to the original default view,

which was the folder tree in the left pane and my documents open in the right

pane. I am not sure how it happened but I think it was after I installed a

piece of software that needed to reboot to complete the install. Is there a

way to change this back for all users without doing each one at a time?
