I've been experiencing high cpu usage from explorer.exe in Windows 10 Pro since a while ago, and this specific dll function seems to be the culprit. Any idea what it's for? I couldn't find anything about it.

  • Use Windows Performance Toolkit to see the cause. Expand the stack of the Explorer.exe instead of svchost.exe – magicandre1981 Dec 20 '17 at 15:03
  • tried that, couldn't find anything with the Ordinal247 function – hikari Dec 20 '17 at 16:46
  • Ordinal247 means you haven't loaded debug symbols. if you need help with reading the ETL file, share the etl (compressed as zip via OneDrive) – magicandre1981 Dec 21 '17 at 15:54
  • If I load the symbols in Process Explorer the name changes to _WrapperThreadProc – hikari Dec 21 '17 at 21:11

    Is it just high CPU usage or is it doing any IO? Have had a similar prob in Win7 that I usually don't notice until it looking through my network disks. How much memory is it using? That was another characteristic of my prob. With lower memory, it fill memory; w/higher memory would usually take long enough to fill that I'd notice it; with 10G network card, it would create a network storm -- which sometimes required puling network cord to regain control. MS support eventually told me to upgrd to Win10 as fix. ;^/. Interesting. – Astara Jun 15 '19 at 6:48
