Do you have also problems using betfair and bet365 at the same time? With VMWare Workstation Player you can use both. VM Workstation allows you to run multiple operating systems including Linux, Windows and more as virtual machines on a single PC. Users can replicate server, desktop and tablet environments on a virtual machine, to run applications simultaneously across operating systems without rebooting.
I have installed Windows 7 in addition to Windows 10. You can easily switch between both of them or use both of them simultaneously.
Important: You have to use the VPN on the virtual machine.
