Description
This policy setting allows you to prevent users from changing the size of the taskbar. If you enable this policy setting, the taskbar is set to the default size and the taskbar size setting is grayed out in the Settings app. If you disable or do not configure this policy setting, users can change the size of the taskbar in the Settings app.
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.
