 title: Operating Systems
+description: An overview of our operating system-related recommendations for all major computing hardware.

 We publish configuration guides for the major operating systems, because you can generally improve the amount of data that is collected about you on any option, especially if you use privacy tools like our [recommended web browsers](../desktop-browsers.md) in place of native tools where appropriate. However, some operating systems will be more privacy-respecting inherently, and it will be much harder to achieve an equivalent level of privacy on other choices.

 title: Windows Overview
 icon: material/microsoft-windows
+description: Microsoft Windows is a common operating system which is extremely non-private out of the box. Our guide covers making some improvements to your computer without replacing your OS.
 ---
 **Microsoft Windows** is a common OS shipped with many PCs by default. The following guides aim to provide some ways to improve privacy and reduce the default telemetry and data stored by disabling some unnecessary features. Over time, Microsoft adds features to the OS which can sometimes rely on cloud-based services. These features will often require certain types of [optional data](https://privacy.microsoft.com/data-collection-windows) that is sometimes sent to remote servers for processing.
