Whenever I try shutting off my pc, there is a screen that says there is an app preventing shutdown. The app, however, has no picture to identify, no title and no description to it. However, when I cancel and try to shut down again, it does so with no issue. How can I identify what is preventing shutdown?
if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
The way win 10 shuts down is affected by startup programs. Its all part of Fast Startup. Win 10 saves a copy of running programs into hiberfil.sys at shutdown, saves a copy of running drivers into ram and puts PC to sleep. On startup, half the files are already loaded.
Its possible this app is part of a startup program.
