Why Is Steam Ending 32-Bit Support and Should I Upgrade PC?

Will My Old PC Still Play Steam Games After Support for 32-Bit Windows Ends?

Valve will stop supporting 32-bit versions of Windows for its Steam client, with the change taking effect on January 1, 2026. This decision primarily affects a very small group of users with older computer systems.

The End of an Era for 32-Bit Systems

The technology industry is gradually saying goodbye to 32-bit computing. You may have noticed that other software developers, such as Mozilla with its Firefox browser, are also discontinuing support for their 32-bit applications. This is not a coordinated effort but rather a widespread and natural progression in technology.

For nearly two decades, the standard for personal computers has been shifting toward 64-bit processors. Both Intel and AMD began producing these more powerful chips long ago, which can handle significantly more information at once. A 64-bit system can access vastly more memory than a 32-bit system, which is limited to 4 gigabytes of RAM. This limitation is a major bottleneck for modern applications and games. The fact that 32-bit architecture has remained relevant for so long is remarkable, but its practical lifespan is ending. Valve’s data confirms this trend, indicating that only about 0.01% of its user base on Windows is still using a 32-bit version.

Why This Change Is Happening Now

Companies decide to stop supporting older technology for several practical reasons. This allows them to allocate resources more effectively and embrace newer, more capable, and secure development tools.

Focusing Resources

Maintaining compatibility with outdated systems requires significant time and financial investment. Engineers must ensure that new features and essential updates function correctly on very old hardware. By discontinuing 32-bit support, Valve can dedicate its full attention to enhancing the Steam platform for the vast majority of its users who are on 64-bit systems.

Improving Security

Modern software relies on modern security measures. Many advanced security features are exclusively available on 64-bit operating systems. After the 2026 deadline, 32-bit Steam clients will no longer receive security updates, creating a considerable risk for anyone still using them.

Core Technology Dependencies

The Steam client is built upon the Chromium Embedded Framework, the same foundational technology that powers the Google Chrome web browser. As Google phases out 32-bit support within Chromium, Valve is compelled to follow suit. They cannot continue to support 32-bit Windows if the underlying components they depend on no longer do.

Operating System Evolution

Windows 10 is the final version of the Microsoft operating system to offer a 32-bit option, and its official support is scheduled to end in October 2025. With the operating system itself becoming unsupported, it is logical for application developers like Valve to align their roadmaps accordingly. The current version, Windows 11, is exclusively 64-bit, signaling a clear direction for the future of the PC ecosystem.

Current statistics show that over 60% of Steam gamers are on Windows 11, with another 35% using the 64-bit version of Windows 10. The decision to phase out 32-bit support is a direct reflection of where the player base already is.

What This Means For You

It is important to understand what will and will not happen after the January 1, 2026 deadline. Your existing 32-bit Steam client may continue to function temporarily. You might still be able to launch the application and play games from your library. However, the client will no longer receive any updates, which has significant consequences.

• You will not get any new features or improvements that Valve introduces to Steam.
• If any part of the client breaks or stops working correctly, it will not be repaired.
• Most importantly, the client will not receive security patches. This leaves your Steam account, personal data, and potentially your entire computer exposed to security threats.

Continuing to use unsupported software is like driving a car for which the manufacturer has issued a safety recall but you never get the fix. It is an unnecessary risk to your digital security.

Your Next Steps: An Action Plan

You have ample time to prepare before the 2026 deadline. Following a clear plan will help you make a smooth transition.

1. Check Your System

First, determine if this change affects you. You can easily check whether your computer is running a 32-bit or 64-bit version of Windows.

1. Press the Windows + I on your keyboard to open the Settings menu.
2. Navigate to System and then select About.
3. Look for the “System type” entry. It will specify either a “64-bit operating system” or a “32-bit operating system.”

If your system is 64-bit, no action is needed. If it is 32-bit, you should begin planning to upgrade.

2. Understand Your Upgrade Options

Moving to a 64-bit system is the only sustainable solution.

Check Your Processor

Some older computers have a 64-bit processor but are running a 32-bit version of Windows. If your “System type” shows “x64-based processor,” you may be able to perform a clean installation of a 64-bit version of Windows. This process will erase all data, so a complete backup of your files is essential.

Upgrade Your Computer

Most machines currently running a 32-bit operating system are old and likely have a 32-bit processor. These processors cannot run a 64-bit operating system. In this scenario, the only option is to purchase a new computer. Any modern PC you buy today will be equipped with a 64-bit processor and operating system.

3. Plan Ahead

Start planning your upgrade now to avoid any last-minute issues. A new computer can be a significant investment, and planning for it ensures a seamless transition. By taking action early, you can ensure your ability to continue gaming on Steam safely and with access to all the latest features.
