Issues that this hotfix rollup resolvesIssue 1

Assume that a UIAutomation client application is running. When pop-up windows appear and then disappear, the UI may stop responding for several seconds.

Cause:

This issue occurs because, when a pop-up window disappears, invalid AutomationPeer objects are left behind. This results in time-consuming operations the next time when a pop-up window appears.
