HERES THE SOLUTION:
The only way I can think of that you had Hyper-V installed and running without you doing it is either
1.) Someone else did it
2.) You did it (or someone else) in windows 8.1 (if you had upgraded from that)
How it got installed doesn't matter.
Now, assuming you still need to know what to do to fix this here a simple step by step guide to fix it.
1.) Right click the start button in windows 10 (This solution will NOT touch VMWARE at all), and click "Control Panel"
2.) Make sure it has the icons listed instead of the groups. Click on "Programs and Features"
3.) On the left side of the window, click on "Turn Windows features on or off"
4.) When the next window opens, locate the check box labeled as "Hyper-V" ans make sure it isnt filled, and that it isnt checked.
5.) Then click on "Ok" button on the bottom of the window. It will refresh and apply the change to the computer. It will probably ask you to reboot. If it does, hit the "reboot now" button.
6.) After the computer restarts, try to launch VMWare again. If it still wont allow you to run a virtual machine, make sure your computer has virtualization enabled. (If you dont know, google it. Lots of tutorials out there). If it is enabled, uninstall Vmware and install it again.
I hope this helped you if you still needed help!!
If you still need help, i can provide a video tutorial if needed.
