Last time I had a fall it was because I figured out a way around my filter, to make sure it dont happen again I changed my account type on my laptop from administrator to regular user (to get around the filter I needed to have administrative rights).
Today I'm so happy I did it because it payed off. My wife was out with the kids and I needed to get on to my laptop to check out an alert from one of our servers, when I finished that I found myself in a position in which I definitely would've had a fall in past - no one home and sitting at a laptop with a filter that I can get around.
This time I didn't fall B"H.
