Steam runs great from my USB (no lag, relatively short load time, sometimes even remembers my account so I don't have to put in the security code). However, after every time I play (CS:GO, btw), I try to eject the USB but it tells me that it is still in use. Even after closing all tabs and all programs it tells me this.
I thought I found a quick fix by pressing "Exit Steam" in the same location where you can eject USBs, but this only worked a couple times. After that, when I exited Steam I was still unable to eject. How can I consistently eject my USB to prevent any problems to my computer or my flash drive?
