Computer Configuration\Administrative Templates\Windows Components\Internet Explorer\Compatibility View User Configuration\Administrative Templates\Windows Components\Internet Explorer\Compatibility View Description
Compatibility View determines how Internet Explorer identifies itself to a web server and determines whether content is rendered in Quirks Mode or the Standards Mode available in the latest version of Internet Explorer. If you enable this policy setting, Internet Explorer uses an Internet Explorer 7 user agent string (with an additional string appended). Additionally, webpages included in this list appear in Quirks Mode.

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.
