You can remove the boot logo that appears when you start Windows XP. This little tweak probably shaves only a few seconds off your boot time but seconds count if you are serious about trying to get Windows XP up and running as quickly as possible.
The only negative is that if you remove the boot logo, you will also not see any boot messages, such as check disk.
To remove the boot logo, follow these steps:
1. Select Start/Run, type msconfig, and click OK.
2. In the System Configuration Utility, click the BOOT.INI tab.
3. On the BOOT.INI tab, click the NOGUIBOOT check box option.
