Windows 11 is a widely adopted operating system in the PC world; hence, Microsoft tries to push its apps and services by default. While most PC geeks are aware of this and clean up their system right after setting up the OS, there's a high chance you might not have. Microsoft's key offerings and services on Windows 11, like Widgets, the Edge browser, OneDrive, Teams, and Copilot, silently eat up your memory during OS startup or in the background and increase your CPU load.
