The Media Creation Tool silently closing is a known hiccup that can be caused by anything from a background process conflict to a temporary glitch in the download.
Since a direct upgrade is your goal, let's bypass the Media Creation Tool entirely and use a method that's often more reliable for this specific task. Instead of the creator tool, I'd suggest you to download the Windows 11 Installation Assistant directly from the official Microsoft website. This tool is literally designed for exactly what you're trying to do: it checks your computer's compatibility and then performs the in-place upgrade from Windows 10 to Windows 11, right within your existing environment, keeping all your files, apps, and settings intact.
Before you run it, let's do a quick prep to smooth the process. Please ensure you temporarily pause or disable any third-party antivirus or security software, as these can sometimes interfere with the upgrade process. Also, if you have any peripheral devices like printers or external scanners disconnected, that can help eliminate potential driver conflicts.
The Assistant will guide you through the rest. It's the most straightforward path to an upgrade when the other tools are being difficult. I'm confident this will get you moving in the right direction.
