Microsoft continues refining Windows 11 with incremental updates aimed at improving everyday usability. The latest Canary Channel release, Windows 11 build 28020.1685, may look minor on paper, but it introduces practical improvements to two areas users interact with constantly: File Explorer and system storage management.

This experimental build enhances the file renaming process by enabling voice typing directly in File Explorer, while also improving the reliability of removing leftover system files such as Windows Update data and the Windows.old folder. These adjustments may seem small, but they address common frustrations many users experience when managing files or reclaiming disk space.

Because the update is part of the Canary Channel, features are being rolled out gradually and may not appear on every device immediately.

Quick Overview of What’s New

These updates focus on everyday workflows, making Windows easier to use while reducing small but persistent frustrations.

Voice Typing Comes to File Renaming in File Explorer

One of the most visible improvements in build 28020.1685 is the integration of Windows voice typing into the file renaming interface of File Explorer.

Previously, voice dictation worked in many text fields across the operating system, but it did not function while renaming files. With this build, users can dictate a file name instead of typing it manually.

How to Use Voice Typing When Renaming Files

1. Open File Explorer.
2. Select a file and begin renaming it (press F2 or right-click → Rename).
3. Press Windows + H to activate voice typing.
4. Speak the new file name.
5. Confirm the rename.

If the feature is active on your device, the voice typing panel should appear while the rename field remains selected. Spoken words are then converted into text directly inside the filename box.

Why This Feature Matters

Although renaming files is a simple task, it happens frequently during everyday computer use. Adding voice dictation provides several benefits:

• Improved accessibility for users who rely on speech input
• Faster naming of long files or documents
• Hands-free workflow for multitasking scenarios
• Better integration of built-in Windows input tools

For users who already depend on voice typing in emails, documents, or chats, extending the feature into File Explorer creates a more consistent experience.

Improved Storage Cleanup for Windows.old and Update Files

The second improvement in this build targets a common storage issue: leftover files from previous Windows installations and system updates.

After major upgrades, Windows creates a Windows.old folder containing the previous operating system version. This allows users to roll back if something goes wrong—but it can also occupy tens of gigabytes of disk space.

Build 28020.1685 improves how Windows handles removing these files through the Settings storage management interface.

Where to Access Storage Cleanup

Users can remove unnecessary system files through:

Settings → System → Storage

From this page, Windows analyzes the system and identifies removable items such as:

• Previous Windows installation files (Windows.old)
• Temporary update data
• Cached system files

The latest update improves the reliability of this process, meaning cleanup operations are less likely to fail or stall.

Important Warning

Deleting the Windows.old folder permanently removes the option to revert to an earlier Windows installation. If you plan to roll back after an update, avoid removing these files.

Why These Changes Are Important

While build 28020.1685 doesn’t introduce major new features, it improves two daily computing tasks that millions of users perform:

1. Faster File Management

File renaming is one of the most common desktop operations. Voice typing adds flexibility and makes the process faster—especially when working with descriptive filenames or organizing large numbers of documents.

2. Better Disk Space Management

Storage space remains a critical concern for devices with smaller SSDs. Previous Windows installations and update leftovers can consume significant space. By improving cleanup reliability directly in Settings, Microsoft reduces the need for third-party tools or manual file removal.

Together, these updates help streamline routine workflows and keep systems running smoothly.

Who Can Install Windows 11 Build 28020.1685

This update is currently available to users enrolled in the **Windows Insider Program Canary Channel.

The Canary Channel receives the earliest experimental builds of Windows, which means:

• Features may change or disappear
• Stability is not guaranteed
• Some features roll out gradually to only a subset of testers

Additionally, leaving the Canary Channel typically requires a clean installation of Windows 11, rather than simply switching to another Insider track.

Connection to the Windows 11 26H1 Development Branch

Build 28020.1685 belongs to the development branch associated with Windows 11 version 26H1.

Unlike regular feature updates, this branch is primarily targeted at new ARM-based hardware, particularly devices powered by Snapdragon X Elite and Snapdragon X Plus processors.

Because of this hardware focus:

• Many existing Intel and AMD systems are not part of the official 26H1 upgrade path
• Testing mainly targets upcoming ARM-based Windows devices
• Canary builds may reflect features intended for future hardware platforms

Why You Might Not See the New Features Yet

Even if your device installs build 28020.1685, the new capabilities might not appear immediately. There are a few common reasons for this.

Gradual Feature Rollouts

Microsoft frequently uses controlled feature rollouts, enabling new functionality only for a percentage of testers at first.

Language and Localization Limitations

Voice typing behavior may vary depending on language support. In early Canary builds, some languages may not yet have fully optimized dictation capabilities.

Experimental Feature Flags

Many Insider features are activated via internal configuration flags. Until these are enabled for your device, the feature remains hidden.

Final Thoughts

Windows 11 build 28020.1685 is not a dramatic upgrade, but it delivers meaningful improvements where they matter most: everyday productivity.

Adding voice typing to file renaming expands accessibility and speeds up routine file management. Meanwhile, the more reliable Storage cleanup system helps users reclaim disk space without digging through legacy tools.

These refinements illustrate Microsoft’s ongoing effort to polish the Windows experience through small but impactful enhancements. For Canary testers exploring the cutting edge of Windows development, this update may quietly become one of those improvements you appreciate every day—even if you barely notice it at first.
