Needless to say, just about every system administrator has come across a situation where they installed a patch or application and then had to deal with a system that didn't work as it was supposed to. To that end, you may also have some trigger-happy user on your network who managed to install an application that later caused you grief. Windows XP helps you better deal with these problems through a great new feature called System Restore - a utility that literally takes your desktop back to a previous point in time.

The System Restore feature is essentially like a built-in rollback facility that helps you move your system to a previous point in time, but with a degree of control. This is an incredibly useful feature - say you install a new driver or application and then want to rollback; you can simply open the system restore wizard and move back to a previous configuration. This is called a restore point, and is created automatically by the system by default after a certain amount of disk activity occurs, after you install software or drivers, or when you manually initiate one. Among the benefits, System Restore will not affect key data directories - it will never roll back your 'My Documents' folders, nor your Internet Explorer favorites and so forth. On top of that, System Restores are reversible - if you don't like where its brought you back to, you can simply reverse the process and go back to where you were, or another restore point if you like.

You have about as much control over the System Restore feature as you like. By default, System Restore runs on all volumes, but you can turn it off on a volume-by-volume basis if you wish. Just be aware that you need 200MB of free disk space on the volume to use System Restore, and that you cannot disable it on the System volume without disabling it on all volumes. System Restore properties are configured from the Control Panel System applet, as shown below:

An individual volume can have its settings changed by clicking on that volume and choosing Settings. The monitoring settings for my D drive are shown below. Note that you can control the amount of disk space that System Restore can make use of:

In cases where you need to restore a previous configuration or wish to create a restore point, use the System Restore tool, found under Accessories, System Tools. This tool works as a wizard, as shown below.

Note the choices to create a new restore point or to actually restore to a previous configuration. I am going to choose to restore to a previous configuration, mainly because the creation of a restore point is exceedingly simple and doesn't require input besides giving it a descriptive name.

If I do choose to do a restore, note that I am presented with a calendar that allows me to choose a restore point date. Any date in bold has an associated restore point.

In this case, the restore point is one that was created automatically by the OS. You will also see ones that result from installing software or drivers, or ones you have created on your own. After choosing a particular restore point, you'll be presented with the following dialog, after which your system will reboot.

System Restore is a great and handy new feature for system administrators managing Windows XP desktops. One note is that Microsoft still states that to uninstall a program, the proper uninstall executable or Add/Remove Programs should be used.

Happy time travel.
