Hey there! This morning, I performed a clean installation of Windows 11, erasing all my drives using Diskpart during the process. After the installation, I completed all the necessary updates. However, when I restarted the system for the first time, three command prompt windows appeared and then closed almost instantly. Now, after that initial reboot, these CMD windows don't show up anymore. I've noticed similar behavior in the past with fresh installations. I created the bootable USB using the Media Creation Tool, and I also ran scans with HitmanPro and Kaspersky's removal tool to ensure everything was clean. I'm just curious if anyone else has experienced these CMD pop-ups and what they might be for.

It’s totally normal! If you made your installation media from a reliable source, like the official Media Creation Tool from Microsoft, those CMD windows popping up are likely just the system setting up drivers or performing initial tasks. No need to fret about it!
I actually took some screenshots of those CMD windows appearing right after the reboot. If it helps, I can share them. It's good to see what’s going on during those brief moments!
That could definitely help! Seeing what’s behind those windows may clarify things even further.
Just a heads up, always make sure you have reliable backups before major installations! Changes to your BIOS or disk settings can risk your data, but in your case, this seems harmless since they’re not persisting after the first reboot.
Yeah, I wouldn’t worry about it either! Those windows usually indicate that drivers are being installed. Since it only happened on the first reboot, it's a standard part of the process after a fresh install.

Thanks for clarifying, that’s a relief!
