Hi. Almost every time I start my PC after updating to 21H1, I am presented with this error in the event log:
Windows cannot load the extensible counter DLL "C:\Windows\system32\sysmain.dll" (Win32 error code The specified module could not be found.).
No BSOD or problems with the PC. I am just not quite sure why this is happening. sysmain.dll exists at the specified location. Does anyone know why this is happening or if it is an issue? Thank you

EDIT: Just realized that I actually only get this error upon launching amazon workspaces. It is not on every startup

see if this helps

right click start button

choose powershell (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:

Repair-WindowsImage -Online -RestoreHealth
and press enter


SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files and restart PC
