Windows 10 – High Harddisk activity on wiatrace.log

You  may notice a high HD activity writing to the wiatrace.log file.

WIA stands for Windows Image Acquisition Library.

This is used if you have a Printer scanner installed. Even if you don’t use the Scanner the log file writes debug info to it.

SOLUTION :

Open the registry and go to :

HKLM\System\CurrentControlSet\Control\StillImage\Trace\wiaservc.dll

Change the value to of TRACEFLAGS from 407 to 0

Check the disk activity again, it should be gone now Smile

 

Alternatively you can stop the Windows Image Acquisition (WIA) Service

Enjoy !

    I noticed this behavior today. Another solution to prevent constant writes to this file is also to stop wia service and then mark both log files (wiatrace.log and wiatrace.bak.log) as read only.

    I will use both solutions, read only and this registry change, just to be sure.

  2. Thanks for the tip! Simple but effective indeed.
