How to Enable or Disable Window Preloading in File Explorer on Windows 11

Windows 11 is constantly evolving to improve how you interact with your files. Starting with build 26220.7271 in the Dev and Beta channels, Microsoft introduced a feature called File Explorer window preloading. This experimental feature aims to make your computer feel snappier by keeping a background process ready to go.

Why use File Explorer preloading?

Why: Microsoft noticed that File Explorer sometimes takes a moment to open, especially after your computer has been idle. By preloading the window, the system keeps the necessary metadata and thumbnail caching ready in your RAM. This reduces the startup delay when you click the folder icon.

What happens when done: Once enabled, your computer will keep a background process active. This ensures that when you click to open a folder, the window appears almost instantly, providing a smoother experience.

How to Check Your Windows 11 Build Version

Before you begin, ensure you are on a compatible version of Windows 11. Press Windows Key + R, type winver, and press Enter. If your build is 26220.7271 or higher, you can use the built-in settings.

Option One: Enable or Disable Preloading via Folder Options

This is the safest way to change the setting without touching system files.

1. Open File Explorer.
2. Click the three-dot menu (…) at the top and select Options.
3. Click the View tab.
4. Look for Enable window preloading for faster launch times.
5. Check the box to enable it or uncheck it to disable it.
6. Click OK.

Option Two: Enable or Disable Preloading via Registry Editor

Warning: Editing the registry can cause system issues if done incorrectly. Always back up your registry before proceeding.

Admin Privilege Required: You must be logged in as an administrator to perform these steps.

1. Press Windows Key + R, type regedit, and press Enter.
2. Navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
3. Right-click in the right pane and select New > DWORD (32-bit) Value.
4. Name it ShouldPrelaunchFileExplorer.
5. Double-click the value. Set it to 1 to enable or 0 to disable.
6. Restart your computer to apply changes.

Hardware Impact and Performance Analysis

You might wonder if this background activity hurts your system. Preloading uses a small amount of system resources to keep the app ready. On modern SSDs, the impact is negligible. However, if you have very low RAM, you might prefer to disable it to free up memory for other tasks.

Summary

File Explorer preloading is a performance-focused feature in Windows 11 designed to reduce launch times. You can easily toggle this via Folder Options or the Registry. While it is safe for most users, those with limited hardware resources may choose to disable it to keep background activity to a minimum.” }
