Transferring Windows 10 Build 1809 Updates to Build 1803: A Comprehensive Guide

Windows 10, with its various update builds, can sometimes leave users in a quandary when they need to update their older build (e.g., 1803) from a newer one (e.g., 1809). While the direct transfer might not be possible through the Windows Update process, there are certain methods that can help. This guide walks you through a step-by-step process to achieve this.

Overview of the Process

Unfortunately, the standard Windows Update process does not support directly upgrading from 1809 to 1803 due to the different nature of these builds. However, there is a workaround involving manually transferring the update files using third-party software.

Method 1: Transfer Update Files via USB

Step 1: Identify the Update Files on Your Updated PC

First, you need to identify the folder containing the update files on your updated PC. On your Windows 10 PC with build 1809, look for a folder named ESD in the C: drive. This folder usually contains the setup files for the latest updates.

Step 2: Copy the Update Files to a USB Drive

If the ESD folder is present and contains the necessary setup files, copy the contents of this folder to a USB drive.

Step 3: Upgrade Your Laptop

Plug the USB drive into your laptop with build 1803 and boot into the Media Creation Tool. From within the tool, select your USB drive as the installation media.

When prompted, you can choose to keep your personal files or delete them (to avoid potential data loss, it is recommended to back up your important data).

This method may upgrade your laptop to build 1809, which is the latest stable build at the time of writing.

Step 4: Address Potential Issues

Some users have reported that simply copying the files may not work due to minor version discrepancies. In such cases, you may need to use third-party software or consult further technical assistance.

Method 2: Utilize Third-Party Software

Several third-party tools are available that can help transfer the Windows 10 1809 updates to a 1803 system. These tools often provide more comprehensive solutions, including better compatibility with different versions of Windows.

Step 1: Download and Install the Third-Party Software

Search for reliable third-party software like NirSoft's Download Renamed Windows Update Files or similar tools. Follow the installation instructions provided by the software developer.

Step 2: Run the Software and Transfer the Files

Run the third-party software and follow its instructions to transfer the necessary update files from your 1809 PC to your 1803 PC. These tools often provide options to selectively transfer specific updates or all available updates.

Step 3: Upgrade Your System Using Transferred Files

Once the files are transferred, you can run the installation process on your 1803 PC, following the prompts to complete the upgrade.

Alternative Methods

If the above methods do not work, you may consider the following alternatives:

Manual Download and Installation

In some cases, you might find that the specific updates you need are available for download from Microsoft's Windows 10 Revision History page. Download the necessary update files and manually install them on your 1803 PC via the Media Creation Tool.

Enterprise Solutions

For business users, some third-party enterprise solutions can help with bulk updates. Tools like EasyWinUpdater can be configured to distribute updates to multiple systems across a network, but these are typically more expensive and may not be suitable for home users.

Conclusion

While directly transferring updates from one build to another can be challenging, there are several methods available to achieve this. Always ensure to back up your data before attempting any upgrade or transfer process to avoid potential data loss. For home users, third-party software and manual file transfers might offer the best solutions.
