Microsoft has rolled out the KB5120998 preview cumulative update for Windows 11 versions 25H2 and 24H2, introducing massive improvements to the taskbar, Start menu, and advanced administrator protection.
- Complete taskbar repositioning (Top, Bottom, Left, Right).
- Granular Start menu customization (Hide Pinned/Recommended sections).
- New 'Administrator Protection' for enhanced privilege security.
- Removal of the legacy WMIC utility.
Microsoft has officially released the KB5120998 preview cumulative update, targeting Windows 11 versions 25H2 and 24H2. This optional update serves as a testing ground for IT administrators to evaluate bug fixes and new features before they reach the general public during next month's scheduled Patch Tuesday. Unlike standard cumulative updates, this preview focuses on quality improvements rather than critical security patches.
Revolutionizing the Taskbar and Start Menu
One of the most anticipated features in this update is the enhanced taskbar customization. Users can now move the taskbar to any side of the screen—top, bottom, left, or right—via Settings. Furthermore, Microsoft has introduced a 'small taskbar' mode, which reduces icon and bar height to maximize screen real estate on smaller devices.
The Start menu has also received a significant overhaul. Users now have the ability to customize the size of the menu and independently show or hide specific sections such as Pinned, Recommended, and All. For those seeking more privacy, the ability to hide the account name and profile picture is now available.
Why This Matters
BozokMedia analysis shows that Microsoft is aggressively pivoting towards a highly modular and personalized User Interface (UI). By giving users control over the taskbar position and Start menu components, Microsoft is addressing long-standing community requests for a more flexible desktop experience.
This update represents a fundamental shift in how Windows manages user-facing customization and administrative security boundaries.
Advanced Security: Administrator Protection
In a move to harden system defenses, Microsoft is rolling out Administrator Protection. This feature allows users to perform administrative tasks using 'just-in-time' privileges, effectively mitigating elevation-of-privilege attacks through profile separation. It is important to note that this feature is disabled by default and must be enabled via Microsoft Intune or Group Policy.

Beyond UI changes, the update improves file searching by automatically indexing frequently used folders. It also enhances system resiliency regarding VPN background processes and introduces a more streamlined update orchestration platform (UOP) for participating third-party apps.
