It sounds like you are describing the new Windows 11 Search interface that appears when you press the Windows key on your keyboard or click on the Search icon in the taskbar. This interface allows you to search for files, settings, and apps on your computer.
If you find that this interface is popping up automatically and interrupting your work, there are a few things you can try.
1. Adjust the Search settings: Click on the Start button and go to Settings > Search. Here you can toggle off the "Show search box on taskbar" option or adjust other search options to your liking.
2. Disable the Windows key: If you find that the Windows key is accidentally triggering the Search interface, you can disable it by using a registry tweak. Open the Registry Editor (press Windows + R, type "regedit" and press Enter). Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced and create a new DWORD value called "DisabledHotkeys" with a value of "5".
3. Disable Cortana: If you don't use Cortana, you can disable it by going to Settings > Cortana > Permissions & History and toggling off the "Hey Cortana" option. This should prevent it from popping up the Search interface.
I hope this helps you resolve the issue with the Search interface popping up automatically. Let me know if you have any other questions or concerns.
