Microsoft appears to be quietly testing one of the most requested Windows 11 features yet — a movable taskbar. New findings from Experimental Build 26300.8289 suggest that development is actively progressing, with Insider builds now containing a semi-functional version of the feature.
Alongside the taskbar discovery, the build also introduces a small but useful upgrade to Storage Settings, giving users more flexibility when resizing partitions.
Windows 11 Movable Taskbar Spotted in Experimental Build 26300.8289
A hidden version of the movable taskbar has surfaced inside Windows 11 Experimental Build 26300.8289. While still incomplete, the feature already allows early repositioning experiments that hint at future customization options.
Current findings suggest:
- Taskbar movement is partially functional
- Debug menus expose internal controls
- Horizontal repositioning shows progress
- Vertical placement remains unstable
- Several UI glitches are still present
The implementation is far from ready for public rollout, but its presence confirms Microsoft is actively testing expanded taskbar flexibility.
For years, users have requested the ability to move the Windows 11 taskbar to the top or sides of the screen — functionality that existed in previous Windows versions but disappeared after the Windows 11 redesign.
Why a Movable Taskbar Matters
The Windows 11 taskbar has been one of the most debated interface changes since launch. Many users criticized the lack of customization compared to Windows 10.
A movable taskbar could offer:
- Better workflow flexibility
- Improved multi-monitor setups
- Easier accessibility preferences
- Familiar layout options for longtime Windows users
- Greater UI personalization
If Microsoft completes development, it could become one of the most impactful Windows 11 quality-of-life upgrades.
Storage Settings Get a Quiet Upgrade
Experimental Build 26300.8289 also introduces an undocumented improvement inside Storage Settings.
When changing partition or volume size, Windows now allows users to switch between MB and GB units directly inside the resize dialog.
Previously:
- Storage resizing only displayed MB values
- Users had to manually calculate GB conversions
Now:
- Users can toggle between MB and GB
- Easier partition planning
- More intuitive disk management experience
This small adjustment removes unnecessary friction for users managing drives or creating partitions.
Experimental Builds Continue Testing Hidden Features
Microsoft frequently uses experimental builds to test unfinished features before deciding whether they will appear in Insider Preview channels.
Build 26300.8289 suggests Microsoft is actively experimenting with:
- Deeper taskbar customization
- Storage management refinements
- Hidden UI debug menus
- Future Windows shell flexibility
Because these builds are highly experimental, features may still change or never ship publicly.
Final Thoughts
Windows 11 Experimental Build 26300.8289 gives enthusiasts an early look at what could become major usability upgrades. The movable taskbar discovery is especially notable, as it addresses a long-standing community request.
Meanwhile, the Storage Settings enhancement may be smaller, but it improves a frequently used system tool in a meaningful way.
If Microsoft continues refining these features, future Insider builds could bring significant improvements to customization and storage management across Windows 11.
