SYMPTOMS

You may be prompted to activate Windows Vista on a computer on which Windows Vista activation was not previously required. For example, this problem may occur on a computer where Windows Vista was preinstalled by an OEM or by using a Volume Licensing installation. The problem does not occur on Retail versions of Windows Vista. For example, the problem does not occur if you purchased Windows Vista and installed the operating system on a computer yourself.

Although this problem rarely occurs, it may occur during typical use of a Windows Vista-based computer. You may also experience Activation Error 0xC004F02A. This error may occur after you restore a customized Windows Vista image that was created by using Volume License (VL) media.

CAUSE

This problem may occur because a specific system setting is removed when a program runs with administrative credentials. The removal of this system setting may cause a BIOS validation check to fail. The BIOS validation check is part of the system activation process. Therefore, you may be prompted to activate Windows Vista, even though the system did not previously require activation. For example, this problem is known to occur when you use Intuit QuickBooks 2007. However, this problem may also infrequently occur when you install other programs or device drivers.

Note This problem does not occur because of an issue in the installed program or device driver. This problem is caused by a system problem in Windows Vista.
