Thanks for your comment.
Are you saying that I will have to re-install all of the recent patches
from MS?
Actually I have checked on Windows Update and on Belarc and neither
suggest that I am in need of re-installing any of my patches.
However, I really am a little apprehensive about leaving all of the
registry keys fully accessible but I have no idea how I should try to
remove permissions from those that don't need it and leave it as is on
those that do (other than doing it manually which would be quite a
mammoth task).
Any ideas?
Paul
