First, before editing your registry
remember to always back it up first, just incase you do
something wrong. The registry when modified is an
instant change and cannot be undone.
BACK UP REGISTRY: So to open the
registry editor click on "START",
"RUN", then type "REGEDIT" (No
speech marks). The registry editor will now open, click
on "FILE" then "EXPORT". From the
save window that appear type in a file name (ie
regback.reg), now click on "SAVE". Your
registry has now been backed up.
