Windows 10 weirdnesses

All of a sudden I found a new program that called itself TiWorker, which I had never heard of before, was active and sucking up 24% of CPU time.  Arrgh.
   So I Googled on it and found quite a bit of discussion.  Not all of it consistent.  The least harmful suggestion was to bring up Windows Control Panel, select "Troubleshooting"  Then select "System and Security" and under that, Run Maintenance Tasks".   The only task that showed was "System Maintenance.  I ran it, and TiWorker disappeared, back to where ever it came from.  System Maintenance didn't brag about what it was doing, but it ran fast and whatever it did made TiWorker go away and stop eating 24% of my CPU.
   Your mileage may vary.
