Whenever I open a File Explorer Window, I see a second, mysterious Window

I recently saw and on my other Computer that whenever I open a File Explorer Window, I see a Second, Mysterious Window. Can anyone please tell me what that is?

    Same here (Windows 11 Build 26100.4946). Strange thing, as soon as i try to track down the origin of this windows (by Sysinternals Process Explorer) it disappears. I will give it a try doing a reboot and then start Sysinternals Process Monitor before starting explorer.exe.

    Same here (Windows 11 24h2 26100.4946). As soon as i try to catch more infos about that strange second preview windows by opening sysinternals process explorer it disappears. I keep analyzing using their process monitor and hope to get more information.

    I am experiencing this issue as well. It's annoying because it forces me to navigate around the 2nd window when I just want to click the explorer icon and go to explorer. I will appreciate any advice for fixing this.

  • Apps like OneDrive, Dropbox, or Google Drive may open auxiliary windows for syncing or notifications, which might appear as separate Explorer windows.
