Libvirt has an autostart feature, which can start your domain on the 
first time libvirtd is started (i.e. during boot).

virsh autostart WINDOWS10

This is probably because cron doesn't run the command as root and hence 
the virsh is no longer connecting to 'qemu:///system' but 
'qemu:///session'. Change it to:

virsh -c qemu:///system start WINDOWS10

But I suggest using the autostart feature instead.
