I connected a USB flash drive to my laptop and it is displayed with this strange icon in the Windows Explorer:
It's certainly not the default icon and I didn't change any icon settings in windows. Its not stored on the flash drive itself, other flash drives have the same icon. I've used Google reverse image search and found a few screenshots that show the same icon but no hints where it comes from.
What is this icon or how can I check which application causes this icon to appear?
Edit: It's a Lenovo laptop and the L on the red background looks suspiciously like the Lenovo logo, so it's probably from some preinstalled software. I would still like to know how and why this icon is shown.
