The second Tuesday of every month is an important day in the tech world. That's the day Microsoft releases its regular updates for Windows, Internet Explorer, Office and other products. Other tech companies, like Adobe, often release updates that day as well.
Microsoft used to call the day Patch Tuesday but it switched the name to Update Tuesday when it started including program updates along with security updates.
The security updates usually include fixes for serious security problems that hackers will take advantage of if you leave them unpatched. Program updates can be any new features that Microsoft wants to add to Windows.
Either way, if you want to keep your computer safe and get the latest features - which you do - it's important to install the updates as soon as they come out. Fortunately, you don't have to mark your calendar; you can set the updates to install automatically.
Even if you know the updates are automatic, there's still one very important step you need to do each month to make sure you're safe. I'll cover what that is further down.
