What is this service doing that it seems to take >90% of CPU? This happened occasioanlly when I used my notebook, and I noticed it when suddenly the fan became loud. I tried to google but some said it's related to Windows Media Player... Does anyone know what is it that this service doing and why it takes CPU Usage so high?

Impersonator

The column from left to right: CPU (91.8%) | Memory | Disk | Network

  • capture a xperf trace of the CPU usage and analyze it with WPA: pastebin.com/pgE11HRD. If you're unsure, zip and upload (OneDrive) the ETL – magicandre1981 Feb 17 '15 at 16:59
