Windows 11 KB5079458 & KB5079464 Beta and Dev Updates Bring Improved Windows Setup

Microsoft just rolled out a fresh pair of updates for Windows 11 Insiders that target a common issue during the operating system setup process. Arrived under the monikers KB5079458 and KB5079464, these releases bring practical changes to system configuration, security, and administrative controls. Also, the same updates offer policy-based removal of preinstalled Microsoft applications.

Better Windows Setup experience

Windows 11 has historically generated your user profile folder name using the first few characters of your Microsoft account email. This usually resulted in awkward names that were difficult to change later.

With the introduction of Build 26220.8062 in the Beta Channel alongside its Dev Channel counterpart Build 26300.8068, Microsoft finally allows you to pick a custom name for your user folder right on the Device Name page during the initial setup.

What this really means is you can skip the registry edits and local account workarounds just to get a clean folder path. You simply need to ensure your chosen name follows standard Windows naming conventions. In case you want to improve Input and Settings, Microsoft has released the Windows 11 KB5079387 update.

Policy-based removal of preinstalled Microsoft apps

Microsoft updated Windows Enterprise and Education policies to let IT administrators remove preinstalled Store applications using a new dynamic list. By navigating the local Group Policy Editor, admins can easily specify which MSIX and APPX programs to uninstall. You find the exact package family name using a terminal command like Get-AppxPackage and add it to the text field. Don’t forget, Windows 11 KB5079387 also hit the preview channel with File Explorer and display improvements just a day ago.

However, there is a temporary limitation. The dynamic list is not yet available within the Intune configuration service provider. Until the dedicated Intune setting launches officially, IT teams must rely entirely on standard Group Policy for testing and implementation.

This update brings several other practical changes. Security tightens as the Windows kernel drops trust for older cross-signed drivers. System restore now gains administrator settings, the Drag Tray becomes Drop Tray, and pen users get a new option to map their tail button to launch Copilot.
