So, for your situation... bottom line.... TeamViewer. It's a
no-brainer as far as I can see.

The only problem with team viewer and any other "software" solution
is booting the computer if it is on a network or requires entry of a
password or any other keyboard input to boot.

Wake-on-LAN: Wake up your computers remotely
whenever you need access.

Windows® system service: Install TeamViewer as a Windows system
service and access remote computers directly after starting Windows
and before the Windows login.

Remote reboot: Restart computers remotely –
even in safe mode.
