Occasionally, EFT will hang or partially crash, such that the window is still open and visible, but completely unresponsive. This can be frustrating, as typical key combos (alt+f4, ctrl+esc, alt+tab, etc) will not hide the window, and even if you manage to open the Task Manager, it opens under the EFT window, so impossible to interact with.
1) Press Win+R (it looks like nothing happens since the run prompt opens under the EFT window)
2) Type "taskkill /f /im escapefromtarkov.exe" (no quotes)
3) Press enter.
In the past ive resorted to logging off from windows and sometimes even a full system restart. Hopefully this helps some of you avoid this hassle and save a few precious seconds of early raid time. If you have a second monitor you can make a batch file and put the icon on your second monitor for even faster task killing.
