How to remove Parallels 12 and Windows 10 virtual machine?

I have a late-2011 MacBook Pro with Mac OS Sierra and am running Parallels 12 with Windows 10 virtual machine. I no longer need the capability to run Windows 10 and want to significantly reduce the clutter on my MacBook, so now want to get rid of Parallels and the virtual machine. I am, however, experiencing difficulty in doing it.
I wanted first to eliminate the virtual machine and Windows 10 and then send the Parallels 12 to the trash. I found Art.ID 5029 which told me how to remove a virtual machine in Parallels. It said first to launch Parallels without starting the virtual machine, and click on the Parallels symbol in the OS X menu bar and select Control Center. but the image shown is not what I obtained, I had a much shorter scroll down list with Control Center at the top. Selecting that brought up the virtual machine, but right clicking on that did not bring up the screen illustrated in the article so I could not find Remove. By now the virtual machine was launched.
Can anyone tell me what I am doing wrong?
I have seen another post which seemed to indicate to first get rid of Parallels to Trash and then eliminate the virtual machine, but I do not understand the logic of that. Surely if I get rid of Parallels I cannot access the virtual machine to remove it?
All suggestions gratefully received!

 

Hi John, please follow the below steps and let us know how it goes:
1. Refer the article to find your Windows virtual machine on Mac & delete it.
2. Refer the article for uninstalling Parallels Desktop 12.

 

Thanks, it worked perfectly. I found the virtual machine in finder and sent it to the trash. We'll see in time whether I have thrown out the baby with the bath water! I then just simply also sent the Parallels applications to the trash as well.
I'm amazed at how much faster my MacBook is as a result.
