How to download and install a fresh portion of this fetid junk?
You can download the ISO from here
https://www.microsoft.com/en-us/sof...459594)(TnL5HPStwNw-WaTVja5C7z2Vs7q82apCPg)()
Choose Windows 10, the first item in the first drop down (not single language at the bottom)
* see note at bottom.
Next choose your language and your bit version (32 or 64 bit to match your system architecture or in the case of an upgrade, to match your currently installed version of Windows).
That will provide an ISO that will boot, upgrade, repair (or clean install) either or both Windows 10 Pro and Home.
*NOTE: In some cases, we've learned that some people have the "Single Language" version installed. In which case you would need that download. It's important that you match the ISO version that you download with your installation.
Once you have downloaded the ISO you can use ImgBurn to burn it to a DVD

OR
Rufus to burn it to a USB ThumbDrive

To create installation media
When you've created the installation media then you can boot from that to perform a clean / custom install
IF you've had Windows 10 installed and activated, you will not need a product key. Microsoft already knows that, that machine is a Windows 10 machine.
IF you are prompted for a product key during the clean custom install, simply choose "I don't have" or "Skip".
