Before you open the System Restore console, you may want to save your work and close all programs since System Restore requires you to restart your computer.
There are two ways to access System Restore through Help and Support or through your All Programs folder.
Through Help and Support:
1. Click Start, and then click Help and Support.
2. Under Pick a Task, click Undo changes to your computer with System Restore.
3. Follow the instructions on the wizard.
Through the All Programs menu:
1. Click Start.
2. Point to All Programs.
3. Point to Accessories.
4. Point to System Tools.
5. Click System Restore.
6. Follow the instructions on the wizard.
Creating a restore point can be useful any time you anticipate making changes to your computer that are risky or might make your computer unstable. If something goes wrong, you select the restore point you just created and Windows XP undoes any system changes made since that time.
