However, you may be able to purchase an activation key through a third-party supplier, such as Whokeys, or vip-scdkeys. You can also try using an activation script.

Typically, Windows 10 LTSC requires a clean install and does not allow you to update from a standard version of Windows 10 (Home or Pro). Normally, this would erase your hard drive and not allow you to keep your data. However, there are ways you can trick your system into thinking it is updating from Windows 10 LTSC. This will allow you to keep your data and apps (even apps that typically don’t come with Windows 10 LTSC). This is NOT supported by Microsoft, and you could permanently damage your computer operating system. It is recommended that you back up any important data you want to keep before attempting to update to Windows 10 LTSC.
