Consider the following scenario: You need to re-install Windows 8 on your computer. Then you need to install the required updates to get it to Windows 8.1, and then install the big update released in 2014 and then quite a few months of updates.
Now if you ever upgrade from Windows 8 to Windows 8.1 it isn’t the easiest upgrade. Quite often the upgrade fails before it even downloads the first MB.
Now if you have ever installed and updated Windows before, you can save probably at least 6 hours of work if you can get ahold of the media that has Windows 8.1 [and even better if it has that big update].
But if you try to use your Windows 8 serial number during the Windows 8.1 installation, the setup will reject it.
To trick Windows into allowing the installation, use the serial number GCRJD-8NW9H-F2CDX-CCM8D-9D6T9 during the installation.
Note: This serial number is a readily available serial number on the Microsoft web site used for Key Management Systems [KMS]. We are just using it temporarily.
After the installation, Windows will reject the KMS serial number above. At that point you can use the serial number from Windows 8.
