Keep getting new windows opening.

have changed folder view options so that 'launch folder windows in a separate process" is unchecked.

tools -> folder options -> open each folder in the same window

Is also checked.

It still does it! very annoying!

Any ideas? Please?!

Try again.. and make sure to click... apply... then.. ok.
Then go under... View... click... apply to folders.. then.. ok.
This then will apply to all folders.

If it's when surfing the net.. You need to go to Internet Explorer > Properties > Advance > Find... Reuse windows for launching shortcuts.. and uncheck.. then apply and ok.
