How to configure Windows XP to start in a "clean boot" state

If your computer is not starting normally, or if you receive errors when you start your computer that you cannot identify, you could consider performing a "clean boot." This operation starts the computer by using a minimal set of drivers and startup programs. This can help you troubleshoot the problem.

This article describes how to configure Windows XP to start by using a clean boot and then how to return Windows XP to a Normal startup type.

After you configure Windows XP to use a clean boot, some programs may not work as expected. When you return Windows XP to a Normal startup type, the programs work again.

This article is intended for a beginning to intermediate computer user.

You may find it easier to follow the steps if you print this article first.

There are two methods to start Windows XP by using a clean boot:

• Method 1: Use the Guided Help
• Method 2: Manually starting XP with a clean boot (advanced user only)

Start with the first method. If it does not work and you are comfortable trying a more advanced method, try the second.

Method 1: Guided Help

• You must be running Windows XP Home Edition, Windows XP Professional, Windows XP Media Center Edition, or Windows XP Tablet PC Edition to install Guided Help.
