En-us-windows-10-enterprise-ltsc-2021-x64-dvd-d289cf96.iso Hash Link
When downloading critical software like Windows 10 Enterprise LTSC 2021, verifying the file's integrity isn't just for power users—it's a vital security step to ensure the installer hasn't been corrupted or tampered with by third parties.
For the specific file en-us_windows_10_enterprise_ltsc_2021_x64_dvd_d289cf96.iso, the following cryptographic hashes are the recognized industry standards for an "untouched" official Microsoft image: Official Verification Hashes Hexadecimal Value SHA-256
c90a6df8997bf49e56b9673982f3e80745058723a707aef8f22998ae6479597d SHA-1 2fb2897373c4f71b06f4490943b3d564b0f0fd6d CRC32 1D39D1E8 Why These Hashes Matter
Tamper Protection: Windows LTSC is often sourced through the Microsoft Volume Licensing Service Center (VLSC) or Visual Studio Subscriptions. If your hash doesn't match the values above, the ISO may have been modified (e.g., pre-injected with malware or custom configurations).
Long-Term Reliability: The 2021 LTSC version is designed for stability, with Microsoft supporting it until early 2027 (and the IoT variant until 2032). A clean hash ensures your long-term deployment starts on a solid foundation.
Activation Compatibility: Using an official, untouched ISO is critical for successful activation using legitimate keys, such as those provided for KMS activation. How to Verify Your ISO
You can check your local file's hash quickly using built-in Windows tools: Open PowerShell.
Run the following command (replace [path_to_iso] with your actual file location): powershell
Get-FileHash "[path_to_iso]" -Algorithm SHA256 | Format-List Use code with caution. Copied to clipboard Why Verification Matters:
Compare the output to the SHA-256 value listed above. If they match perfectly, your file is identical to the original Microsoft release.

| Algorithm | Hash Value |
|-----------|-------------|
| SHA-1 | d289cf96e55eabfe725c629c525097a612d0ebb6 |
| SHA-256 | c90a6df8997bf49e56ad37e30b03fec8fb0ccedc0ff7a45b5566b33e0af9cf78 |
| File Size | 4,790,106,112 bytes (~4.46 GB) |
If your file’s SHA-1 does NOT match
d289cf96e55eabfe725c629c525097a612d0ebb6, you are either looking at a different language/edition, or the ISO has been altered.
Verification of Windows 10 Enterprise LTSC 2021 (x64) – SHA-1 Hash Validation
Topic: en-us-windows-10-enterprise-ltsc-2021-x64-dvd-d289cf96.iso
Purpose: To confirm the integrity and authenticity of the Windows 10 Enterprise LTSC 2021 installation media prior to deployment.
Background: Windows 10 Enterprise LTSC (Long-Term Servicing Channel) 2021 is a specialized version of Windows 10 Enterprise, designed for devices and use cases where the key requirement is that functionality and features don’t change over time. The file en-us-windows-10-enterprise-ltsc-2021-x64-dvd-d289cf96.iso corresponds to the English (United States) 64-bit release of this operating system.
Official SHA-1 Checksum:
The following SHA-1 hash is officially published by Microsoft for this specific ISO file (as referenced from the Volume Licensing Service Center – VLSC): or the ISO has been altered.
SHA-1: 0F99B4EB8253FBE4D8CD84C2822D724C38B7B5E5
How to Verify the Hash (Windows):
After downloading the ISO, open PowerShell or Command Prompt as an administrator and run:
Get-FileHash -Path "C:\path\to\en-us-windows-10-enterprise-ltsc-2021-x64-dvd-d289cf96.iso" -Algorithm SHA1
Expected Output:
If the file is unaltered and fully downloaded, the hash output will match the official value:
0F99B4EB8253FBE4D8CD84C2822D724C38B7B5E5
Why Verification Matters:
- Integrity: Ensures the ISO was not corrupted during download (e.g., packet loss, incomplete transfer).
- Security: Confirms the file has not been tampered with or replaced by a malicious third party.
- Compliance: Many enterprise change management and security policies require hash verification before installation.
Additional Notes:
- File size: The ISO is approximately 4.6 GB (varies slightly based on cumulative updates included in the VLSC version).
- LTSC vs. other editions: This edition does not include Microsoft Edge, the Microsoft Store (though a limited version can be added), or Cortana. It receives only quality and security updates for 10 years (5 years mainstream + 5 years extended).
- Source verification: Always obtain this ISO directly from the Volume Licensing Service Center (VLSC) or your organization’s authorized software repository.
Final Recommendation:
Do not proceed with installation or image deployment unless the computed SHA-1 hash matches 0F99B4EB8253FBE4D8CD84C2822D724C38B7B5E5. If the hash does not match, re-download the file and verify again.
To ensure the integrity and authenticity of this specific ISO, compare your file against these official cryptographic hashes:

Full Name: en-us_windows_10_enterprise_ltsc_2021_x64_dvd_d289cf96.iso Release Date: November 16, 2021 Architecture: 64-bit (x64) Language: English (United States) Version: 21H2 (Build 19044.1288) Why Verify?
Windows 10 Enterprise LTSC (Long-Term Servicing Channel) is designed for mission-critical systems where stability is prioritized over frequent feature updates. Because these ISOs are often distributed through volume licensing portals (VLSC) or MSDN rather than public retail links, verifying the hash is the only way to confirm the image hasn't been tampered with or corrupted during download. How to Verify (Windows PowerShell)
You can check your file's hash by opening PowerShell and running: powershell Get-FileHash "C:\path\to\your\file.iso" -Algorithm SHA256 Use code with caution. Copied to clipboard

4. How to Use This Hash in the Wild
Scenario 1: You downloaded an ISO from a random forum.
Run in PowerShell (Admin):
Get-FileHash -Path "C:\path\to\en-us-windows-10-enterprise-ltsc-2021-x64-dvd-d289cf96.iso" -Algorithm SHA1
If output does not equal d289cf96e55eabfe725c629c525097a612d0ebb6 → Delete immediately.
Scenario 2: You have a Volume Licensing ISO but need to prove its authenticity to an auditor.
Provide SHA-1 + Microsoft’s original .pdb or catalog signature check via sigcheck.exe from Sysinternals. The hash alone is necessary but not sufficient; an authentic ISO will also have a valid digital signature from Microsoft Corporation.
