Select the 64-Bit LTSC version for your region/language to begin the download. Once the download is finished, use the ISO file to create a bootable USB installer and use it to install Windows 10 LTSC.

I recently bought myself a new desktop PC.. I like getting ex-lease office stuff as they are usually a lot quieter than most DIY builds (unless you put in a lot of effort), and they are good value.

Once installed, install updates as usual ... the last update to Windows 10, and there may also be LTSC-based remix "distros" like in the preceding paragraph.

Windows 10's Enterprise Long-Term Servicing Channel (LTSC) focuses on a version of the company's previous operating system that will focus on the essentials of the operating system alone.

This way, the company is cutting down the available time to avoid installing Windows 10 feature updates in half for users of devices running LTSC releases (previously known as 'mission-critical').
