Chapter 20. Maintaining and troubleshooting your computer

In this section:

Windows 8.1 has several built-in features to help you keep your computer running at its best, improve performance when needed, guide you through troubleshooting tasks, and help you restore your computer when you experience a problem that you can’t resolve by using other methods. In this section you’ll learn about many of these features, including but not limited to creating a recovery drive, using ReadyBoost, configuring Windows Update, resolving problems by using Action Center and various troubleshooting wizards, using Advanced Startup Options to perform automated checks and fixes, and refreshing and resetting your PC when all else fails.

Creating a recovery drive

A recovery drive can help you repair your computer even if the computer won’t start. When you create this drive, you can also copy a manufacturer’s recovery partition if your computer came with one (and if the drive you’re saving to is large enough to hold it). It’s best to create this drive before a problem occurs, versus wishing you had after the fact. The best way to start is to purchase and then connect an empty USB disk (or thumb drive) that is at least 256 MB, although you can also use a DVD.

Computers store data that is needed only temporarily in physical random access memory (RAM) located inside your device. Temporary data can be information being sent to a printer, or it can be data needed to perform calculations; it isn’t generally data you’d save to your hard drive. In general, the more RAM a computer has, the faster it will perform.

Unfortunately, it’s often difficult to add more RAM to a device. When it is an option, it’s invasive and can be expensive. If you want more RAM but don’t want to go this route, you can use a technology called ReadyBoost to improve performance. ReadyBoost acts like RAM and serves the same purpose, but it requires only a USB stick or compatible memory card.

Periodically, Microsoft sends out updates to its operating system to make improvements or fix problems that have surfaced. They also address security issues. These updates can apply features changes too. You can set how you want Windows 8.1 to download and install these updates, although the recommended settings are best in most cases.

The Action Center keeps track of problems you encounter, looks for solutions, and if solutions are found, notifies you of the fix. It also monitors your computer to make sure that it’s doing all it is configured to do, and it lets you know whether there are any problems. For example, if you have File History enabled and your drive becomes full or is disconnected, the Action Center will notify you. If your antivirus program is out of date and can’t be updated on its own, it’ll tell you about that too.

When you save data and apps to your hard disk or view or download temporary Internet files, those bits of data can be stored at various locations across your hard disk. Over time, the out-of-date bits of data can cause your computer performance to slow down. Disk Cleanup allows you to erase stray data (among other things) to improve your computer’s performance.

Sometimes you will need to restart your computer. It might be frozen, the display might be distorted, or you might be asked by a software application to restart the computer to apply changes. There are many ways to restart your computer, including accessing the Power icon by using Ctrl+Alt+Del or from the Settings charm. The easiest way is to right-click the Start button.

Windows 8.1 comes with several built-in troubleshooting wizards. If you know what type of problem you’re having, you can use one of these wizards to try to resolve the problem. Troubleshooting wizards are available in the following categories: Programs, Hardware and Sound, Network and Internet, and System and Security.

What happens in a wizard differs depending on the one you select, but the process is the same. You select the type of problem you’re having, and the wizard prompts you to try various fixes until the problem is resolved.

Microsoft Fix It is an online troubleshooting tool. If you’re having a problem that is common to a lot of users, you might be able to find an entry for the issue you’re having, as well as an automated fix for it. If you find the solution that you need, you can give Microsoft Fix It permission to run the automated solution for you. You don’t have to have a problem to explore Microsoft Fix it, so work through the steps here so that you’ll know what to do when a problem arises.

Remote Assistance lets you ask a person you know to help you resolve a problem over the Internet or a local network. You send an invitation (generally via email), the person accepts the invitation and connects to your computer, and then you give that person permission to fix your computer for you by taking control of it and resolving the problem themselves.

Troubleshooting with Windows Task Manager

Task Manager is a utility that keeps track of the various programs and processes that are running on your computer, and it offers you an option to end those programs and processes manually, should one stop responding. Task Manager is extremely useful to professional computer technicians, and there’s a lot more that you can do with it than this. However, it’s important to know how to end applications that don’t respond to any attempt to close them, because this might save you from having to completely restart your computer. It might also resolve problems currently caused by the errant, albeit frozen, application.

Sometimes you’ll need to start your computer in a way other than booting to the hard disk. For example, if the computer won’t start, you might need to boot it with a Windows 8.1 DVD or USB drive. You might want to use Advanced Startup options to make use of the recovery drive you created at the beginning of this section to recover the computer if it’s having problems. You might also want to troubleshoot your PC by selecting tools such as System Restore, Startup Repair, and Startup Settings. These tools can help you recover from all kinds of startup problems.

Here are a few of the items you might want to try if you’ve been unable to repair your computer successfully by using other techniques:

If your computer has so many problems that the only way you know how to resolve them is to completely start over by formatting your computer or restoring from your computer’s recovery drive (and you’ve already tried System Restore, Startup Repair, and similar options), try refreshing your PC. When you refresh your PC, only third-party programs, web browser addons, printer software, scanner software, and other desktop apps are removed, but apps from the Windows Store, your personal settings, and your personal data (documents, music, videos, pictures, and so on) will remain intact.

If your computer has so many problems that the computer is extremely unstable, and if you’ve tried all of the troubleshooting techniques outlined here, including refreshing your PC, you might have to reset your PC. However, for the most part, you’ll use this feature only when you want to give your computer away or recycle it. When you do, the computer is reset to factory defaults. All of your apps, data, and desktop applications will be removed from your computer, as will your personal (local) settings, network information, and data about connected hardware. Your PC will be formatted. You will be able to log in with your Microsoft account, and restore your apps and saved settings and access data from SkyDrive, but this is still a major step to take. Try everything else first.
