For years, Windows users have expressed frustration about File Explorer. This crucial part of the operating system feels slow on Windows 11. From lagging folder navigation to delays when starting the app, the experience often contradicts Microsoft’s promise of a smooth interface.
Now that Windows 10 has reached the end of support and millions are switching to Windows 11, Microsoft faces pressure to fix these performance issues. In response, the company has started testing a new feature aimed at speeding up File Explorer’s launch and responsiveness. This feature is a background preloading system that aims to cut down on startup delays.
Although still in testing, this improvement represents Microsoft’s most concrete effort yet to tackle a long-standing complaint.
A New Background Preloading Feature in Testing
In the release notes for Windows 11 Insider Preview Build 26220.7271, Microsoft announced that developers are trying out a feature that preloads File Explorer in the background before it is opened. The goal is straightforward: make sure the app feels much faster as soon as someone clicks its icon.
According to Microsoft:
“Most users will not notice any visible change, but File Explorer should hopefully launch faster when you need to use it.”
This approach draws on a method used in other applications. By getting key processes ready ahead of time, it reduces the wait time users face when starting the app.
Currently, preloading is an opt-in feature for Windows Insiders in the Dev and Beta channels. This means it might take months to become available in public builds, if at all.
Will the Feature Ship to Consumers? No Guarantees Yet
Despite the interest, Microsoft has been careful with its language. The company states it is “exploring” the feature, which suggests uncertainty. Many experimental features in Insider builds never reach end users, either because they don’t pass testing, cause unintended issues, or provide little benefit.
This means there’s no guarantee that this performance upgrade will appear in the next major Windows update.
However, industry observers view its inclusion in both Dev and Beta builds as a hopeful sign. Features that stay in the Dev channel are often too early for public release, while those in the Beta tier typically indicate Microsoft is testing user interest and stability.
Why File Explorer Feels Slow on Windows 11
File Explorer’s slow performance is one of the most common complaints about Windows 11. Several factors contribute to this issue:
- The redesigned user interface introduced extra animations and updated controls that can slow down loading times.
- Integration with cloud services like OneDrive can add delays, especially when syncing is active.
- Frequent background indexing, which aims to improve search speed, often makes the app feel heavy on less powerful hardware.
- Old code mixed with new UI components creates slowdowns for some actions.
Microsoft has released several minor fixes since the launch of Windows 11, but many users still report slow performance, especially when opening large folders, network locations, or system folders.
The new preloading feature is the company’s most direct attempt yet to tackle this launch lag.
How Users Can Enable the Feature (If They Have Access)
For those using the latest Windows Insider Dev or Beta build, the new preloading option is available starting this week.
Users can turn it on by:
-
- Opening File Explorer
- Going to Settings
- Finding the option labeled “Enable window preloading for faster launch times”
- Switching it on
Microsoft encourages testers to report any bugs or regressions through the Windows Feedback Hub, emphasizing that feedback from these early users will help determine if the feature will be released publicly.
A Quirky Workaround Still Speeds Up File Explorer—But With a Catch
Interestingly, some users have found a separate Windows 11 bug that also speeds up File Explorer, though unintentionally.
The trick is simple: press Ctrl + F11 twice to toggle File Explorer in and out of full-screen mode. This action temporarily resets parts of the UI and can make moving around feel faster.
However, there are downsides.
This workaround:
- Disrupts other aspects of the Windows UI, including minimizing behavior and certain app transitions
- Can cause some interface elements to behave erratically
- Is not a reliable or stable way to boost performance
Microsoft has never officially acknowledged the bug, but it is well-known on enthusiast forums. The existence of such a workaround highlights the need for a proper solution, something Microsoft’s new preloading feature aims to deliver.
Alternative File Explorer Apps Offer Relief—With Mixed Results
Before Microsoft began exploring performance enhancement, some users turned to third-party file managers such as:
- Directory Opus
- Files App (from the Microsoft Store)
- XYplorer
- FreeCommander
These apps often provide faster performance, extra features, and more customization. However, their integration with Windows 11 features—particularly OneDrive, Quick Access, and the modern context menu—can be inconsistent. For many users, the convenience and compatibility of File Explorer remain unmatched.
This is why a native fix is essential; most people just want File Explorer to work smoothly.
A Long-Awaited Improvement as Windows 11 Shifts to a Post-Windows 10 Era
With Windows 10’s end of support, millions of users face a tough choice: upgrade to Windows 11 or remain on an unsupported system that poses increasing risks.
For those who delayed the switch due to changes in the UI or performance issues, improvements like the File Explorer preloading feature could make the experience more appealing. Microsoft feels the growing pressure to show that Windows 11 offers more than just visual updates, but real improvements to everyday usability.
While the company has emphasized AI features like Copilot, core system performance remains crucial for shaping public opinion.
This new experiment suggests Microsoft is paying attention.
What Comes Next?
The next few months will decide if File Explorer preloading becomes a permanent feature. Microsoft will assess:
- Stability and crash reports
- Impact on system memory usage
- User feedback
- Effect on startup times
- Compatibility with cloud services and third-party extensions
If testing goes well, the feature could be included in a future Moment update or the next major annual Windows release.
For now, the company remains cautious. However, the fact that Microsoft is finally addressing one of Windows 11’s most frustrating issues signals a renewed focus on performance—something many users have been waiting for.
