When Microsoft ends support for XP in a few months
I've always encouraged people to bite the bullet and upgrade to a new operating system when getting a new computer, rather than clinging to an old OS they are more comfortable with. However, I know from hanging out on this forum that some people are very reluctant to move on, or have an older computer that they don't want to get rid of quite yet. Microsoft will end support for XP in spring 2014, which means that security and other updates will no longer be produced for this more than 10 year old OS. For those who are still using XP, this means that you will be more vulnerable to new Internet threats and viruses.
However, if you are in this category, there are a few things you can do, nonetheless, to be a little more secure. The link below is to a useful article I just came across that gives details on why you will be vulnerable and tips on things you can do to be a little more secure after XP support ends.
