This will not delete the  "Chrome Apps" folder itself.

Is this only used for uninstall? If so, ShellUtil already mostly covers
uninstalling all shortcuts that point to the chrome.exe being uninstalled, and
will fully cover it after huangs' CL @
https://codereview.chromium.org/14287008/.

This code could thus be removed. It would only need to be replaced by a new
entry to delete the "Chrome Apps" folder which the code in ShellUtil isn't aware
of yet.

Noted. It should delete the folder if it becomes empty after this. I think that
is suitable to delay for another CL.
I think you are talking about uninstall of Chrome. This is used for
uninstallation of a particular app, which I don't believe huangs' code will
cover.

Actually, I just did it here (not too big after all).
