Murray from Tustin, CA

Episode 1214

The first line of defense is online behavior. The number 1 priority should be to keep the computer updated.

How can I use my VPN with dual monitors?

Monica from Diamond Bar, CA

Episode 1210

Monica uses two monitors on her computer, but when accesses her work's VPN, it only supports one monitor. Is there an option for her? Leo says that Microsoft Terminal Services Client can be forced to use both monitors by adding "/span" to the command line shortcut on the desktop that looks like this: %windir%\system32\mstsc.exe /span. She can also do it in her settings. The chatroom also says that if the monitors have different resolutions, that can cause issues as well. Another thing to check is to see if the Windows license permits it. Windows Ultimate will, but home won't.

That can be found in the settings. Cortana will get better over time.
