Oberrich is a small, community-focused software publisher whose GitHub presence centers on concise, single-purpose utilities that quietly undo Windows 11’s more polarizing visual decisions. Its catalog is presently anchored by Win11 Toggle Rounded Corners, a lightweight open-source tool that exposes a hidden registry switch to flatten the operating-system’s signature rounded window chrome with one click. While the portfolio is still narrow, the project exemplifies the publisher’s broader philosophy: surgically targeted tweaks that restore user choice without background services, advertising, or bundled payloads. Typical use cases include enterprise IT departments that need a uniform, legacy-friendly desktop aesthetic for Remote Desktop farms, retro-computing enthusiasts who prefer the sharper angles of Windows 10, and productivity users who reclaim every pixel on small laptop screens. The utility ships as a portable executable and an optional PowerShell script, making it easy to automate across fleets via SCCM or Intune. Because the code is published under the MIT license, auditors can verify that only the DWM border attribute is touched, leaving system stability intact. Oberrich’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always resolving to the newest release and supporting batch installation alongside other applications.
