One of the greatest things you can do for your computer is patches.

Microsoft offers patches for all of their products as everyday there are new vulnerabilities discovered and there are teams of programmers at all of the major software companies cleaning up problems that they did not now existed earlier.

Here in Calgary, whenever doing maintenance work on a PC I do the patchng necessary to make sure that you do not have to worry about your computer getting out of date. Also there is a feature that I can turn on in Windows that makes it check often for patches and automatically installs them..
