Configure SMB v1 client driver

Configures the SMB v1 client driver's start type.

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!

For Windows 7 and Servers 2008, 2008R2, and 2012, you must also configure the "Configure SMB v1 client (extra setting needed for pre-Win8.1/2012R2)" setting.

To restore default SMBv1 client-side behavior, select "Enabled" and choose the correct default from the dropdown:
* "Manual start" for Windows 7 and Windows Servers 2008, 2008R2, and 2012;
* "Automatic start" for Windows 8.1 and Windows Server 2012R2 and newer.

Changes to this setting require a reboot to take effect.
