IERefreshElevationPolicy Function

IERefreshElevationPolicy Function

Tells Windows Windows Internet Explorer processes to refresh elevation policies from the registry.

Syntax

HRESULT IERefreshElevationPolicy(VOID);

Return Value

Returns S_OK if successful, or an error value otherwise.

Remarks

Typically, elevation policies are loaded when the first Internet Explorer process loads. As a result, changes to elevation policies do not take effect until all current processes have ended and Internet Explorer is restarted. If you modify elevation policies and wish your updates to be effective more quickly, call IERefreshElevationPolicy after modifying elevation policies. When you do so, Internet Explorer reloads elevation policies when they're next used.

Other articles which talk about where in the registry to set ElevationPolicy entries during installation of an ActiveX control should also make mention of this new api function. For example, the first hit in Google for "elevationpolicy":

IERefreshElevationPolicy doesn't solve the problem

aidtopia | Edit | Show History

This doesn't say in what context to call IERefreshElevationPolicy. The blog post announcing this API suggests calling it in your extension installer after adding the new elevation policy. But the installer is typically running as the Administrator (often a different user) or as a service (automatic updates). Unfortunately, IERefreshElevationPolicy doesn't seem to signal all instances of IEUSER to reload the elevation policies, just the one for the current user. So this is still a Catch-22. How can the installer trigger other a policy cache refresh for other users?
