Computer Configuration\Administrative Templates\Windows Components\Internet Explorer User Configuration\Administrative Templates\Windows Components\Internet Explorer Description
This policy setting allows you to revert to the Internet Explorer 8 behavior of allowing OnUnLoad script handlers to display UI during shutdown. This policy setting may be needed to fix compatibility problems with particular web applications. If you enable this policy setting, OnUnLoad script handlers display UI during shutdown. If you disable or do not configure this policy setting, OnUnLoad script handlers do not display UI during shutdown (default behavior in Internet Explorer 9).

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
