Change method

Note Image Note

This entry affects file scanning only. It does not affect the standard background file change detection that Windows File Protection provides.

This entry can be superceded by a policy included in Windows 2000. While the Set Windows File Protection scanning is enabled, the system ignores this entry. The setting of the Set Windows File Protection scanning policy is stored in the value of Sfcscan in the Policies subkey. If Windows File Protection or System File Checker does not operate as expected, check to see whether a policy is in effect.

Windows File Protection only scans when the current user is an administrator of the computer.
