How to Install Windows 11 LTSC on Old Unsupported Computers
In this guide, you’ll learn how to install Windows 11 IoT Enterprise LTSC, a version designed specifically for older unsupported computers. This evaluation copy from Microsoft allows you to test the system until a stable release is available in early 2024. It’s crucial to be aware that once installed, you cannot uninstall this version or revert using your recovery partition. Therefore, proceed with caution, as you’ll need to perform a clean installation should you wish to switch back to your previous operating system. This guide will cover everything from system requirements to successful installation.
Step 1: Understand Windows 11 LTSC
Windows 11 LTSC (Long-Term Servicing Channel) is tailored for devices that require a stable operating system without the frequent updates of standard Windows versions. Familiarizing yourself with this can help in determining if it meets your needs. It is designed to provide less feature-bloat while ensuring security updates are prioritized. If your use-case involves older hardware or specific applications, LTSC might be the right fit for you.
Step 2: Check System Requirements
Before you start, ensure your machine meets the minimum system requirements for Windows 11 LTSC. These generally include:
- Processor: 1 GHz or faster with at least 2 cores on a compatible 64-bit processor or System on a Chip (SoC).
- RAM: At least 4 GB.
- Storage: 64 GB or larger storage device.
- UEFI firmware with Secure Boot capability.
- TPM version 2.0.
- DirectX 12 compatible graphics / WDDM 2.x.
If your system meets these requirements, you can proceed with the installation.
Step 3: Download Windows 11 LTSC ISO
You will need to download the official Windows 11 LTSC ISO from the Microsoft website. Visit the Microsoft official page and locate the download section for the LTSC version. Ensure you download the evaluation copy appropriate for your architecture (64-bit). This ISO file is necessary to create a bootable USB drive that you will use for installation.
Step 4: Prepare Bootable USB Flash Drive
To install Windows 11 LTSC, create a bootable USB drive using the downloaded ISO. You can use tools such as Rufus or the Windows Media Creation Tool. Here’s how to use Rufus:
- Insert your USB flash drive (ensure it is at least 8 GB).
- Open Rufus and select your USB device under ‘Device’.
- Choose the ISO file you downloaded under ‘Boot selection’.
- Click on ‘Start’ to create the bootable USB. This process will format your USB drive, so back up any important data first.
After the process completes, your USB drive will be ready for the installation.
Step 5: Begin Installation of Windows 11 LTSC
With your bootable USB ready, plug it into your target computer and reboot. Access the BIOS/UEFI settings (usually by pressing F2, Del, or Esc during startup) and configure the boot order to prioritize USB drives. Save changes and exit.
Your computer should boot from the USB drive, and the Windows 11 installation setup will start. Follow the on-screen instructions to begin the installation process, selecting your language, time, and keyboard preferences as prompted.
Step 6: Prepare Partitions
During the installation, you will reach the screen where you can select or create partitions. If you intend to perform a clean installation:
- Select the partition where you want to install Windows 11 LTSC.
- If necessary, delete existing partitions and create a new primary partition for the installation. Be cautious—this will erase all data on those partitions!
Ensure the selected partition has enough space (minimum 64 GB) before proceeding.
Step 7: Complete the Setup of Windows 11 LTSC
Once you have prepared your partitions, the installation will continue. Follow the prompts to configure your user settings, connect to your network, and sign in with your Microsoft account. After the setup is complete, Windows 11 LTSC will finalize settings, and you will be able to use your operating system.
Extra Tips & Common Issues
Throughout the installation process, it’s essential to keep the following points in mind:
- Ensure you have stable power supply during installation to avoid interruptions.
- Prepare a backup of your data since this process will require clean installation.
- Remember that once you install LTSC, reverting back to another version of Windows will necessitate a clean installation.
