This MiniTool post explains Windows Server LTSC (Long-Term Servicing Channel), detailing its features, supported versions, download methods, and installation.

What is Windows Server LTSC?

Since September 2023, Microsoft offers two Windows Server release channels: LTSC and the Annual Channel (AC). LTSC prioritizes stability with a traditional lifecycle of updates, while AC offers more frequent releases for faster innovation. LTSC is ideal for businesses needing major version updates every 2-3 years, providing 5 years of mainstream and 5 years of extended support. It offers two installation options: Server Core (no GUI) and Server with Desktop Experience.

Windows Server LTSC Versions:

Microsoft currently offers Windows Server 2022 and Windows Server 2019 (version 1809) as LTSC versions, each in Standard and Datacenter editions. Note that mainstream support for Windows Server 2019 LTSC has ended, but extended support continues until January 9, 2029.

Downloading Windows Server LTSC:

• Windows Server 2022 LTSC: Download from the official Windows Server 2022 download page. Select the 64-bit edition in your preferred language.
• Windows Server 2019 LTSC: Download the ISO image from the Internet Archive (link provided in the original article).

Verifying the ISO:

Before installation, verify the downloaded ISO. Mount the ISO, navigate to the Sources folder, locate install.wim, install.swm, or install.esd. Open an elevated Command Prompt and run: dism /Get-WimInfo /WimFile:x:\sources\install.wim /index:1 (replace 'x' with the drive letter). Check the "Version" and "ServicePack Build" to confirm it's the correct LTSC version (20348.xx for 2022 or 17763.xx for 2019).

Installing Windows Server LTSC:

1. Connect a USB flash drive.
2. Use Rufus to create a bootable USB drive from the ISO.
3. Boot from the USB drive and follow the on-screen instructions to perform a clean installation. Remember to back up your data first, as a clean install will erase everything on the target drive.

Checking if a Server is Running LTSC:

1. Open Windows PowerShell as administrator.
2. Run the command: Get-ComputerInfo | fl WindowsProductName,OSDisplayVersion.
3. The output will show the product name and version. An LTSC version will be clearly identified.
