We all know about windows updates which arrive every month and keep our PC safe from the latest security worries. However more and more exploits are being discovered in other programs which we run on our PCs. It is also important to keep these programs up to date.
An easy way of doing this is to run a small program called PatchMyPC.
Download the program to your pc and run it. It will scan your PC for programs for which upgrades are available and then download and install the upgrades, all with a couple of clicks.
