Just going threw some things and came across this. There is alot that can be changed from here but i wanted to inform about this one because you can have some fun with it. You can add a string to what is logged on websites. So now when people are going threw their log files they will see a creative or funny or maybe even mean message from you. I just thought it was kindof cool. Anyways if you want to do it

Go to start and then run and type out gpedit.msc
Now double click on windows settings and then internet explorer maintenance and then user agent string. From there you can type whatever you want
