All operating system vendors provide patches and updates to their products to correct security problems and to improve functionality. Microsoft provides monthly patches on the second Tuesday of each month. From time to time, Microsoft will issue an “off schedule” patch to respond to a particularly serious threat. To update any supported version of Windows, go to “Start” and select “Windows Update” or “Microsoft Update.” Follow the prompts to select and install the recommended patches. Other operating system vendors have similar functionality. Ensure that you know how to update and patch any operating system you.
