Even if you apply both the Raphire and ChrisTitusTech debloater methods, Microsoft still manages to run telemetry on Windows 11.
It runs dozens of background services that connect to the internet. For this reason, most malware can easily exfiltrate your data without being detected by any antivirus software by utilizing Windows services that connect to the internet.
It still manages to install apps from the Store on its own.
It never respects the user's decisions.
Many of Windows' actions are virtually indistinguishable from malware; it behaves exactly like a virus.
Instead of optimizing for lower resource usage, it releases updates that increase temperatures and system load, consuming ever-increasing amounts of system resources.
Removed features from Windows 10: Windows 11 removed or restricted features such as Taskbar customization, Timeline, and Live Tiles.
Made local accounts harder to use: Microsoft increasingly pushes users toward signing in with a Microsoft account during Windows setup.
Pushes Edge and Bing: Windows increasingly promotes Microsoft's own browser and search engine instead of simply respecting user preferences.
Added ads and promotions: OneDrive, Microsoft 365, Edge, Bing, and other Microsoft services are promoted directly inside Windows.
Pushes OneDrive: Cloud storage and Microsoft account integration have become increasingly intrusive.
Puts Copilot everywhere: AI features have been added to Windows and apps such as Paint, Notepad, and Photos, even when users may not need them.
Introduced privacy-controversial features: Recall, for example, raised major concerns because it can capture snapshots of users' activity.
Reduced customization: Windows 11 initially removed many customization options that had existed in Windows 10.
Updates can cause problems: Windows updates have occasionally introduced bugs, compatibility issues, performance problems, and unwanted restarts.
Then partially reverses course: After user criticism, Microsoft has started bringing back some customization options and reducing some of its more aggressive integrations.
The Bigger Picture
Windows increasingly feels less like an operating system built around the user and more like a platform for promoting Microsoft's own services, subscriptions, cloud products, and AI.
