On my machine (i5, 12 GB RAM) WIN10 is teasing me right now. Either CPU is high or it produces a high traffic on my hd. Either due to updates or Avira Antivir "just scanns" or telemetry or other threads are running. Looked at every single Task, it's ok but... Every day there's something else updating, etc. Very annoying at the moment. At lot of friends complain about that, too.
