Hi,
In your case I would probably wait on the paid upgrade and run the beta (tech preview) as Windows 10 support isn't added to Workstation 11 yet either. I think Workstation 11 works, but please test before you buy.
Try VMware Workstation, Run Linux and Windows in a Virtual Machine | United States
Trial version are full functional and complete versions, you only need a license to activate after the 30 days trial.
The preview version is here and is works until December 31 (official version would normally be released by that time):
