How to Run Windows Update on Your Windows 8 Tablet
Perhaps the most important maintenance task of all, Windows Update automatically sends security patches to your Windows 8 tablet every Tuesday. If possible, your tablet installs the patches immediately. If the patches require you to restart your tablet, however, Windows Update waits for you to restart your tablet, and then installs the patches as your tablet starts up again.
If you want to make sure your tablet is up-to-date with Microsoft’s security patches, or if you want to check for any waiting updates, follow these steps:
From any screen, slide your finger inward from the right edge to fetch the Charms bar, then tap the Settings icon.
When the Settings pane appears, tap the words Change PC Settings from the bottom edge.
When the PC Settings window appears, tap Windows Update from the bottom of the left column.
The PC Settings screen shows the Windows Update section.
Your tablet normally checks daily for updates and installs them automatically, but if you’re impatient or expecting an update, tap the Check for Updates Now button to check immediately for any waiting updates:
After the updates have downloaded, you can install them immediately by fetching the Charms bar, tapping the Power icon, and choosing Update and Restart from the pop-up menu. (If you don’t see that option, the updates have politely installed themselves, without your having to restart your tablet.)
Windows Update requires a working Internet connection to download new updates or check for new ones.
Windows Update only updates your tablet’s operating system — Windows 8 or Windows RT. It doesn’t update your apps, — the mini-programs available through the Windows Store.
