How to Check Windows 10 LTSC 2021 Compatibility

Before proceeding with the installation, it’s crucial to ensure that your hardware is fully compatible with Windows 10 LTSC 2021. Here’s how you can check:

1. Use the Compatibility Check Tool

Microsoft provides tools to help you check your system’s compatibility with Windows 10 LTSC 2021. You can use tools like PC Health Check to identify whether your hardware supports the new version.

2. Check for Driver Availability

Visit the device manufacturer’s website and confirm that drivers for your hardware are available for Windows 10 LTSC 2021. While LTSC doesn’t receive regular feature updates, hardware drivers are still crucial for performance and stability.

3. Verify BIOS/UEFI Compatibility

Ensure your system’s firmware (BIOS/UEFI) is up-to-date. Older firmware can cause compatibility issues or prevent the system from properly recognizing Windows 10 LTSC 2021.

Check Your Processor Compatibility

Processor compatibility is critical for a successful installation. Windows 10 LTSC 2021 requires a 64-bit processor. To ensure compatibility:

1. Check the Processor’s Architecture

Windows 10 LTSC 2021 requires a 64-bit processor. To determine whether your processor supports 64-bit architecture, check your processor’s specifications on the manufacturer’s website.

2. Check Processor Performance

While Windows 10 LTSC 2021 can run on processors that are 1 GHz or faster, for optimal performance, it’s recommended to use a multi-core processor with a higher clock speed (2.0 GHz or more).

3. Enable Virtualization Support

If you plan to use virtualization technologies like Hyper-V, make sure your CPU supports Intel VT-x or AMD-V (virtualization extensions). These features must be enabled in BIOS/UEFI to take full advantage of virtualization.

How to Install Windows 10 LTSC 2021: Different Methods

There are several ways to install Windows 10 LTSC 2021. Choose the method that best suits your needs.

1. Installing via Bootable USB Drive

This is the most common method for a fresh installation of Windows 10 LTSC 2021.

  • Create a Bootable USB Drive: Download the Windows 10 LTSC 2021 ISO from Microsoft's official website or through your Volume Licensing Service Center. Use the Media Creation Tool or a third-party tool like Rufus to create a bootable USB drive.

  • Set Up Windows Deployment Services (WDS): This method requires a WDS server to share installation files over the network.
  • Configure PXE Boot: Set your target devices to boot via PXE (network boot). The installation files will be transferred over the network to the devices, and you can follow the standard installation process.

3. Installing from an Existing Installation (Upgrade)

If you already have an older version of Windows 10, you can perform an upgrade to Windows 10 LTSC 2021.

  • Download the ISO: Get the Windows 10 LTSC 2021 ISO from Microsoft’s website.
  • Mount the ISO: Right-click on the ISO file and select Mount. This will create a virtual DVD drive.
