If you run into problem with Vista, you can easily restore your system to a previous state. For example, if you install a device driver or other software that does not agree with the rest of your system, you can return your computer to the state it was in before you installed it. This is made possible using the System Restore tool.
If necessary, you can start the System Restore tool from the command prompt. This is useful if you can not start your computer normally or in Safe Mode. To start the utility using this method, restart your computer and press F8 during startup. From the boot options, select Safe Mode with a command prompt. You can then log on to your computer using an account with administrative privileges.
The last step is to launch the System Restore tool. You can do this by typing the following command at the command prompt.
