Clean install of Windows 10 without needing to first do an Upgrade install

I found the instructions on ghacks.net today.

Note: In later versions of Win10, these instructions are not required. Just install a fresh copy of Win10 and enter the original Win7/8 product key and it should activate!

You can also just boot from a USB drive to WindowsToGo and pre-activate any system for Windows 10 - see here.

I have not tried it but it looks useful!

Tip: Before you run this operation, make sure to backup the existing Windows installation so that you can restore it should things go wrong.
Here is what you need to do to clean install Windows 10 on a computer system, without needing to run the Win10 Upgrade first and then wipe and re-install.
  1. You need a Windows 10 DVD or ISO image. If you don't have one get it from here. Download the tool from Microsoft's website to create the ISO image. Make sure you pick the right architecture and version.
  2. Burn the ISO, mount it or extract it.
  3. Navigate to the folder \Windows\x64\sources or \Windows\x32\sources and drag&drop the file gatherosstate.exe to the desktop.
  4. Run the file from the Desktop. It creates GenuineTicket.xml on the desktop. This file is needed, so copy it to a USB drive or other location.
  5. Run a clean install of Windows 10 afterwards on the system using the ISO. Make sure you skip the product key.
  6. Once you are done and in Windows 10, copy the file GenuineTicket.xml to C:\ProgramData\Microsoft\Windows\ClipSVC\GenuineTicket. The folder is hidden by default. If you cannot see it, select File > Options > View > Show hidden files, folders and drives in File Explorer.
  7. Reboot the PC.
The next time you boot into Windows 10 it should be fully activated. You can verify that easily with a tap on Windows-Pause. This opens the System Control panel and the system's activation status at the bottom of the page.

Tip: Copy the gatherosstate.exe file to your E2B USB drive and add these instructions into a .txt file on the E2B USB drive. Then you can use this process on any Win7/8 system.
