It’s late in the evening and you’re at home, using your computer to update a document you need for work the next day. You make your final changes, save the document, and submit it to print. You turn to the printer, only to find nothing there. You print the document again, and again get nothing. Thinking that maybe there’s something wrong with the printer connection, you decide to reboot your computer.

But you’re getting error messages that you’ve never seen before. After clicking on two or three dozen “Okay” buttons, your computer finally starts booting up again, and you sigh in relief. Until you start getting error messages stating that certain files are out of date or can’t be located. Eventually your computer comes back up, but it seems that everything has gone wonky. Programs load with errors, or don’t load at all. Utilities that worked fine last night lock up when you try to launch them, including your virus-scanning software. In short, something’s very, very wrong.

Ordinarily this would mean taking your computer into a repair site and have a tech look at it to determine the problem. The fix could be as simple as running a few utilities on the computer, or as complex as rebuilding the hard drive from scratch. Even the simpler solution can be expensive. But if you are running Windows XP as your operating system, you may not need to go into a blind panic. A utility included with Windows XP called System Restore allows you to recover your hard drive from a previous point in time. In effect, you’re turning back the clock to a point in the past where your computer was working properly.

Give Me a Reason
Why would you restore your computer to, say, yesterday afternoon’s settings? There are plenty of reasons why you might want, or need, to do so. The incident described above could be caused by a virus that got through your computer’s firewall and installed itself on your computer. Remember the new game you installed on your computer late last night? It could have overwritten system files in the operating system, replacing them with older files, or deleting required files altogether. Maybe somebody got a little trigger-happy with the mouse when selecting files to erase from the system, deleting required system files. Then there’s always the possibility of an “act of God”, like a power outage or power surge, which may have corrupted system data on the computer.

Convinced? Good. So how does System Restore work? Let’s take a look.

Start at the Beginning
When Windows XP is installed on a computer system, the System Restore utility is turned on by default, so you don’t have to do anything to start the process. System Restore also automatically creates “restore points”, points in time you can select for restoring your computer. They’re usually created when a new program is installed, or updates to the existing system are implemented (generally through the Internet). Good news.

Unfortunately Windows XP isn’t consistent about the frequency of creating these restore points. You might go two or three days before an incident occurs where the operating system feels it’s necessary to create a restore point. Not-so-good news. However, you can go in yourself and manually create a restore point any time you want, say, just before you install a new program. If you’ll do this on a regular basis, even once a day, you’ll have a good number of points from which to restore if you ever need to.

A Good Recovery Place
You may want to create a restore point of your own, or need to find a restore point to recover your system. In either case, you start the same way. In the menu bar at the bottom of the desktop, click on Start, then Help and Support (the blue question mark icon). Under “Pick a Task” in the right column of the window that appears on your screen, select the option marked Undo changes to your computer with System Restore. This launches the System Restore utility, bringing it up in a new window.

If you want to create a new restore point, select the second option in the menu and click Next. You can enter an appropriate description for this restore point, and then click on Create. Windows XP automatically attaches your description and the date and time from your computer system to the restore point and adds it to the calendar list. Click on Close and that’s it – you’ve created a restore point. You can go on with your work (or play) now.

When You Need Some Restoration
If you need to restore your system to an earlier date and time, in the System Restore menu select the first option in the menu and click Next. You can use the calendar on the left side of the window and the restore points described on the right side of the window to pick the particular restore point you wish to use. Once you’ve selected the desired restore point, click on Next, and then Next again to start the restore process. Don’t power down your computer during this process, as you could end up with some serious issues if the restore process doesn’t complete properly. (Helpful hint: Don’t do a restore if there’s a possibility you might have a power outage, such as during a thunderstorm!) Once the restore is done, the computer reboots, you log in, and there you are – your system is the way it was at the date and time of the selected restore point.

Helpful Hints
You’ll avoid a lot of grief if you follow a few guidelines when using System Restore.

Regularly create manual restore points. It only takes a few minutes to create a restore point. Even if you only do this once or twice a week, it gives you that many more options to choose from when you need to select a restore point.

ALWAYS create a restore point before adding anything new to your computer! Whether you’re adding a new printer, installing a second hard drive, or upgrading your favorite software program, create a restore point before starting the process. If anything happens and problems develop, you can restore your computer to the way it was before the installation started.

Save important data before starting a restore. Remember that anything that has changed on your computer between the time of the restore point and the time you begin the restore will be reset to the way it was at the time of the restore point. If your restore point is from ten days ago, every program and data file you have added to your computer in that ten-day period will be gone. Files that were on the computer at the time of the restore point and that you have deleted since then will be back on the computer after the restore. So if you have files on the computer that you want to keep, copy them to diskette or RAM stick, or burn to a CD, before you start the restore process.
