I would like to explain: Microsoft did not decide to install Copilot as a separate application on your computer.
As you are probably aware, Windows is continually updated. This is how Windows evolves over time. The updates are not additions to Windows, they are Windows.
The Windows operating system now includes artificial intelligence, of which Copilot is a visible example. As Windows continues to evolve through updates, we will see more artificial intelligence on our computers, which means, among other things, more of Copilot.
I want to be very clear about this: Even though it's on our computers as part of Windows, nobody is required to use Copilot, just as nobody is required to use Microsoft Edge or Windows Media Player or Windows Fax and Scan or the OneDrive app, etc. ... just because it's there doesn't mean we're supposed to use it. I myself don't use any of those things. Since I'm not using them, they aren't doing anything. Nevertheless, they remain part of the operating system, for the people who do want to use them, and for software developers who use them in their apps.
