To disable client-side processing of the SMBv1 protocol, select the 'Enabled' radio button, then select 'Disable driver' from the dropdown.
WARNING: DO NOT SELECT THE 'DISABLED' RADIO BUTTON UNDER ANY CIRCUMSTANCES!
To restore default SMBv1 client-side behavior, select 'Enabled' and choose 'Manual start' for Win7/2008R2, or 'Automatic start' for Win8.1/2012R2/newer.
For Win7/2008R2, you must also configure the 'Configure SMB v1 client (extra setting needed for Win7/2008R2)' setting.
Changes to this setting require a reboot to take effect.
