Report: Windows 10 Pro (Version 1809, 64-bit) ISO Download

2. MSDN (Microsoft Developer Network) Subscribers

If you have an active MSDN or Visual Studio subscription, you can legally download any older Windows 10 build, including Version 1809 (64-bit Pro). This is the top safest method.

4. Internet Archive (archive.org)

As a last resort, the Internet Archive stores untouched, verified ISOs. Search for Windows 10 Pro 1809 64-bit untouched ISO. Check the SHA-1 checksum against Microsoft’s official values (see table below).

Problem: Windows Update tries to force upgrade to 22H2

Solution: Use Windows Update Blocker or Group Policy:

Run gpedit.msc
Navigate to: Computer Config → Admin Templates → Windows Components → Windows Update
Enable "Select when Preview Builds and Feature Updates are received" and set deferral to 365 days.

Installation & Clean Install Tips

If you are installing this ISO:

Product Key: You will need a valid Windows 10 Pro product key. The ISO is universal; the key determines if you get Home or Pro.
No Drivers: Since this is an older ISO, newer hardware (CPU/GPU) released after 2018 may not have drivers included in the installation package. You may need a USB drive with LAN/Wi-Fi drivers handy to connect to the internet post-install.
Immediate Updates: Once installed, Windows Update will likely try to force-upgrade you to a newer version (like 21H2 or 22H2) immediately. You must pause updates if you intend to keep version 1809 for testing purposes.

Important: Support Status & Security Considerations

Before you download windows 10 pro version 1809 64bit iso, you must understand its lifecycle:

End of Servicing (Home/Pro): November 10, 2020
End of Servicing (Enterprise/Education): May 11, 2021

Warning: Version 1809 no longer receives security updates. Using it online exposes your system to unpatched vulnerabilities.

Solution: If you must use 1809, isolate the machine from the internet or use it only in a controlled offline environment. For daily drivers, consider Windows 10 22H2 or Windows 11.

3. Rufus + Fido Script

The open-source tool Rufus (for creating bootable USBs) includes a Fido script that can download older Windows ISOs directly from Microsoft’s servers. Here’s how:

Download Rufus (from rufus.ie).
Click the down arrow next to "SELECT" and choose "Download".
Select "Windows 10" → "Pro" → "Version 1809 (build 17763.xxx)".
Rufus will fetch the official ISO from Microsoft’s CDN.

⚠️ Important Warning Before You Download

We strongly recommend against installing Version 1809 for daily use. Because it is an outdated version (End of Life), it contains unpatched security vulnerabilities and is incompatible with many modern software optimizations.

If you are downloading this for a specific legacy software requirement or a virtual machine test environment, proceed with the methods below.

Method 2: Windows Media Creation Tool (Workaround)

Limitation: The standard Media Creation Tool currently downloads Windows 10 22H2 (latest version), not 1809.
Workaround: Use the older version of Media Creation Tool specific to 1809 (e.g., MediaCreationTool1809.exe). Microsoft no longer links this on the main site, but the file can be found via Microsoft’s own servers (digital signature still valid). Proceed with caution and verify digital signatures.
