That post was mine. Solved by using ShellExView from here:

disabling non MS items one at a time till problem fixed. It was an Nvidia
file causing it and it seems others with Nvidia graphics had same problem.

In Windows Explorer If I right click on anything in the left hand pane
then the screen just goes white and the program stops working, although
left hand clicking is okay, this was one of the reasons why I abandoned
Vista and now it's happening in Windows 7, any clues please?
That question came up a day or two ago, or at least
I saw a reference to an Nvidia shell extension that has the
ability to freeze things. You don't need the Nvidia shell extension,
so it can be disabled without harm.

If that isn't it, you'll need to review what Shell Extensions are in
there, and identify the culprit. It could be some useful little
program you've installed. For example, 7ZIP installs a context
menu item, so it could be using one of those as well. Maybe a
"Take Ownership" is installed that way as well. Have a look and
see what's hiding in there. The Nvidia one is the only one I know
of that freezes stuff.
