A Guide to securing Windows XP
Internet Explorer Security
Internet explorer 7 in Windows XP has some good security features which we should be aware of.
If you open Internet explorer 7, Select Tools, then Internet Options then select the Content tab, then the Settings tab for AutoComplete, you will see the AutoComplete settings like the figure below.
From AutoComplete Settings area you can set which features you would like Internet Explorer 7 to remember. If you de-select all of these then you will not save any web addresses, usernames and passwords, which would be your safest option, and which I do myself.
You can also delete your Browsing history. Open Internet Explorer 7, Select Tools, then Internet Options then select the Delete button under Browsing History, and you will see a dialogue like the figure below. At the bottom there is a Delete all option, which would delete all history. Other users will now not be able to view any of your browsing history, and web sites you have visited, any words you have typed into the search bar, and any usernames and passwords previously saved will have been deleted as well.
It's a good security feature within XP and Internet Explorer 7, so I would advise you make the most of it.
