CAUSE

This problem occurs because the System File Checker utility cannot locate certain Windows installation files. These Windows installation files are described in the System log event messages in the "Symptoms" section.

Note These Windows installation files are not required by Windows XP Media Center Edition 2005.

WORKAROUND

To work around this problem, make sure that the Windows installation files are available when you run the sfc.exe /scannow command, and then click Cancel every time that you receive an error message. The System File Checker utility will successfully complete the scan operation.

Note If no Windows installation files are available, you may have to cancel the error message many times. In this scenario, you may want to cancel the whole operation. To do this, follow these steps:
  1. Drag the Windows File Protection dialog box to another location on the desktop.

    Note After you move the Windows File Protection dialog box, you will see a second Windows File Protection dialog box. This second Windows File Protection dialog box contains the following message: Please wait while Windows verifies that all protected Windows files are intact and in their original versions.
  2. Click Cancel in the second Windows File Protection dialog box.
  3. Click Cancel in the first Windows File Protection dialog box, and then click Yes.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
