This policy setting determines whether Clipboard contents can be synchronized across devices. If you enable this policy setting, Clipboard contents are allowed to be synchronized across devices logged in under the same Microsoft account or Azure AD account. If you disable this policy setting, Clipboard contents cannot be shared to other devices. Policy change takes effect immediately. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\OS Policies\Allow Clipboard synchronization across devices (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System!AllowCrossDeviceClipboard
