How to Do a System Restore With Windows XP
- 1). Log on to your computer as the administrator. You cannot use System Restore on a guest account.
- 2). Click the Windows "Start" menu button, point to "All Programs" or "Programs," and point to "Accessories." Point to "System Tools" and click "System Restore" to launch the System Restore utility.
- 3). Click the "Restore my computer to an earlier time" radio button on the "Welcome to System Restore" page and click "Next." This launches the "Select a Restore Point" page.
- 4). Click the most recent restore point in the "On this list, click a restore point" list and click "Next." Click "Next" again on the "Confirm Restore Point Selection" page. Windows shuts down, and System Restore automatically reverts your computer to the date you selected. When the process completes, Windows restarts automatically.
- 5). Type your administrator password and log on to Windows XP.
