// Summary:
|
|
// On upgrade from W2K, it is possible (under certain conditions) that the Active Desktop
|
|
// gets turned ON automatically. This is bug #154993. The following function fixes this bug.
|
|
//
|
|
// Details of why this happens:
|
|
//
|
|
// In W2K, it is possible to enable active desktop components, hide icons, lock the components
|
|
// and then turn off active desktop. But, all the details (like what AD components were ON etc.,)
|
|
// was persisted in the registry. When such a machine is upgraded to Whister, bug #154993 surfaces
|
|
// because of the following reason:
|
|
// In Whislter, ActiveDesktop is turned on/off silently based on whether any desktop component is
|
|
// on etc., As a result when a W2K machine (with AD off) is upgraded to Whistler, the AD will be
|
|
// turned on automatically, if one of the following is true:
|
|
// 1. If the desktop icons were off.
|
|
// 2. If the active desktop components were locked.
|
|
// 3. If any active desktop component is ON; but, not displayed because AD was OFF..
|
|
// Therefore on upgrade from a Win2K or older machine, we check if the AD is OFF. If so, then we
|
|
// need to check for conditions 1, 2 and 3 and change those settings such that AD continues to be
|
|
// OFF even after the upgrade. The following function OnUpgradeDisableActiveDesktopFeatures ()
|
|
// does precisely this.
|
|
//
|
|
// Returns: TRUE, if any setting was modified to keep the active desktop in the turned off state!
