I have a Z840 WS running Windows 7 64 Professional (It was downgraded from windows 10 when I purchased the machine). The OS resides on an HP Turbo drive which is my c: drive. I want to replace (upgrade) windows 7 with clean install of Windows 10 on the HP turbo drive. What is best way to accomplish this?

from within windows 7, download the windows 10 install image (usb key or DVD image)
once the win 10 install media is made, FROM WITHIN THE WIN 7 OS, go to the win 10 media and run the win 10 installer which is SETUP.EXE
the win 10 installer will check/confirm a valid win 7 license/activation and then procede to install a clean win 10 install and also give you a valid win 10 digital activation license
once the first win 10 activation is done, all future win 10 installs to this motherboard can be done directly without first having win 7 installed
note that MS can deactivate this win 10 licenseing method at any time since it's a unoffical way to upgrade
