RegDisablePredefinedCacheEx function (winreg.h)

Disables handle caching for all predefined registry handles for the current process.

Syntax

LSTATUS RegDisablePredefinedCacheEx();

Return value

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is a system error code.

Remarks

This function does not work on a remote computer.

Services that change impersonation should call this function before using any of the predefined handles.

For example, any access of HKEY_CURRENT_USER after this function is called results in open and close operations being performed on HKEY_USERS\SID_of_current_user, or on HKEY_USERS.DEFAULT if the current user's hive is not loaded. For more information on SIDs, see Security Identifiers.
