Fix Windows Input Experience High Memory Usage

If the Windows Input Experience (TextInputHost.exe) is using a large amount of memory, the fix is to restart the process, update Windows, and check for corrupted system files. This article explains why this happens and gives step-by-step solutions that work on Windows 10 and 11.

What Is Windows Input Experience?

Windows Input Experience is a system component that handles touch keyboard, handwriting recognition, and voice typing. Its main executable, TextInputHost.exe, runs in the background whenever you use any text field. Normally it uses only 20–60 MB of RAM. When it spikes to hundreds of megabytes or more, it can slow down your whole system, especially on devices with 4–8 GB of memory.

Why Does It Use So Much Memory?

There are several common causes for high memory usage by TextInputHost.exe:

Corrupted system files – damaged Windows components can cause the process to loop or leak memory.
Outdated Windows – older builds had bugs that caused memory leaks in the input stack.
Third-party keyboard or IME software – apps that add input methods can conflict with the built-in service.
Fast Startup – this feature can leave the process in a bad state after shutdown.
Many language packs or keyboards – each installed language adds resources that the process must load.

How to Fix It (Step-by-Step)

Try these fixes in order. Most users resolve the issue with the first or second step.

Restart the process – Open Task Manager (Ctrl+Shift+Esc), find “Windows Input Experience� under Processes, right-click it, and choose End Task. Windows will restart it automatically when you next click a text field.
Run Windows Update – Go to Settings > Windows Update and install all pending updates. Microsoft has patched known memory leak issues in recent versions.
Run System File Checker – Open Command Prompt as administrator and run sfc /scannow. This repairs corrupted system files. After it finishes, restart your PC.
Run DISM – In the same Command Prompt, run DISM /Online /Cleanup-Image /RestoreHealth. This fixes the Windows image that SFC relies on.
Disable Fast Startup – Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, then uncheck “Turn on fast startup.� Restart your PC.
Remove unnecessary languages and keyboards – Go to Settings > Time & Language > Language & Region. Remove any language packs you don’t use, and under each language, remove extra keyboards you don’t need.

What If the Problem Comes Back?

If the memory usage returns to high levels after a few days, the issue is likely a persistent bug or a conflict with third-party software. Try these additional steps:

Update your graphics driver – the input experience uses GPU acceleration, and outdated drivers can cause memory bloat.
Run a clean boot – disable startup programs and see if the issue stops. If it does, re-enable programs one by one to find the culprit.
Check for malware – some malicious programs disguise themselves as system processes. Run a full scan with Windows Defender.
Reset the app – in Settings > Apps > Installed apps, search for “Windows Input Experience,� click the three-dot menu, and choose Advanced options > Reset.

Common Misconceptions

Many users think that ending the process is harmful. It isn’t – Windows restarts it automatically. Another misconception is that disabling the touch keyboard service will fix the issue. That service is needed for many accessibility features, and disabling it can break voice typing and handwriting. Instead, focus on the fixes above.

When to Consider a System Reset

If you’ve tried all the steps and the memory usage still climbs to hundreds of MB, a more drastic step may be needed. You can try a Windows repair install (using the “Keep my files� option) or a full reset. Before doing that, make sure you back up your data. A repair install reinstalls Windows but keeps your personal files and most apps. This often resolves deep system corruption that SFC and DISM can’t fix.

Frequently Asked Questions

Is it safe to end the Windows Input Experience process?

Yes. It’s a system process that restarts automatically when needed. Ending it will not harm your system, and it’s a quick way to clear memory bloat.

Why does TextInputHost.exe appear multiple times in Task Manager?

Windows creates a separate instance for each input method or language that is active. This is normal, but if you have many languages installed, each one consumes memory.

Will disabling the touch keyboard reduce memory usage?

It can, but it’s not recommended because it breaks features like voice typing and handwriting. Better to fix the underlying cause.

Does this affect gaming performance?

Yes, high memory usage by any background process can reduce available RAM for games. Fixing it can improve performance, especially on systems with limited memory.

Can a third-party antivirus cause this issue?

In rare cases, yes. Some security software interferes with system processes. Try temporarily disabling your antivirus to test, but re-enable it immediately if the issue persists.

How much memory is normal for Windows Input Experience?

Typically 20–60 MB. If it consistently stays above 100 MB or climbs over time, that’s abnormal.
