Nobody likes to have to reinstall Windows. Nobody. In the past it has been a major headache, with finding or creating the recovery / installation media and if you can find and / or read the product key from the Certificate of Authenticity (COA). But with the Windows 10 online upgrade, things just got a whole lot easier.
There may come a day when you may need to repair or reinstall Windows 10. In previous versions of Windows, you had to create the manufacturers branded recovery disks or use the hidden recovery partition to reinstall Windows. Or maybe you were one of the luckily ones that got an OEM disk. Either way, you had to have the same media that originally installed the operating system to do a reinstallation.
The really big problem was allot of people didn't know they needed to make the recovery disks. They only found out after their hard drives crashed. At that point, they have only two choices; contact the manufacturer to find out if they sell the recovery disks. Some do, some don't. But the cost for replacement recovery disks is going to be less than the second option, which is to purchase a new installation disk.
Now if you're one of the millions that have upgraded from Windows 7 or Windows 8.1 to Windows 10 online, you now have a digital license. You can use the Windows 10 Media Creation Tool from Microsoft to create either a bootable USB drive or an ISO file that can be burned to a blank DVD. And the cool thing is that you can make the installation media on another computer, just in case your Windows 10 computer needs to be repaired.
All you need for hardware is a USB drive (8GB or larger) or DVD burner and a blank single-side or double-side DVD. What you need to know about your version of Windows 10 is what language, what edition (Home, Pro, etc.) and what architecture (32-bit or 64-bit). Most consumers use the Home edition as the Pro edition does cost more. Unless you specifically order your computer with the Pro edition or your computer is part of a domain, it's probably the Home edition. And most computers nowadays run 64-bit versions of Windows.
The next thing is the product key. In previous versions of Windows, once the operating system was installed the product key was stored on the hard drive. With Windows 10, once the operating system is installed, the product key is stored on the cloud. So if you're doing a clean / repair installation of Windows 10 on a system that has already been activated, you will not need to enter a product key when prompted for one. You can just click on the Skip button and Windows 10 will automatically activate when it gets online. It's one of the coolest features of Windows 10 you hope you never have to use.
