How to Install Windows 10 Enterprise LTSC 2019 (Complete Step-by-Step Guide)

Windows 10 Enterprise LTSC 2019 is designed for long-term stability, minimal bloat, and maximum performance. If you have an Original License Key, the installation and activation process becomes smooth and secure.

Berikut langkah instalasinya:

1. Prepare What You Need

Before starting, make sure you have:

Minimum 8 GB.

✔ A computer or laptop where Windows will be installed

There are two recommended methods.

  1. Download Rufus (free tool).

  2. Insert your USB drive.

  4. Under Boot selection, choose the LTSC 2019 ISO.

  5. For most modern devices:

    • Partition Scheme: GPT

    • Target System: UEFI

  6. Click Start.

  7. Wait for the process to complete.

(Only works if you already have an LTSC ISO)

Not recommended unless you know what you’re doing.

3. Boot Into the USB Installer

  1. Plug the USB installer into your computer.

  2. Restart your device.
