Title

The first-run prompt to sign into Office365 must be disabled. (Cat II impact)

Discussion

Office 365 functionality allows users to provide credentials for accessing Office 365 using either their Microsoft Account, or the user ID assigned by the organization. Access to Office 365 will not be permitted; only locally installed and configured Office 2013 installations will be used. Since the ability to sign into Office 365 will be disabled, this policy, which determines whether the Office First Run comes up on first application boot if not previously viewed, will also be disabled.

Check Content

Verify the policy value for User Configuration >> Administrative Templates >> Microsoft Office 2013 >> First Run >> "Disable Office First Run on application boot" is set to "Enabled". Use the Windows Registry Editor to navigate to the following HKCU\Software\Policies\Microsoft\Office\15.0\firstrun Criteria: If the value 'bootedrtm' is REG_DWORD = 1, this is not a finding.

Fix Text

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> First Run -> "Disable Office First Run on application boot" to "Enabled".
