When you try to log on to Windows XP, you may receive the following error message:
The evaluation period for this copy of Windows has ended. Windows cannot start. To continue using Windows, please purchase and install a retail copy of the product.
This behavior may occur if your evaluation copy of Windows XP has reached the end of the 180-day evaluation period, or if the date and time on the computer has been changed. A date change, if enough, can make the 180-day evaluation period expire earlier than it is scheduled to expire.
To resolve this issue, use the appropriate method.
