What I've done to solve this:
create a simple batch script to delete te etilqs files from the c:\windows\temp file at system startup.
This way, you have the most chance of being able to delete most files, and you won't have to do any manual actions on it.
the script roughly looks like this (tempty.bat):
del /F /Q /A:H etilqs_*
del /F /Q etilqs_*
I've added a log file option as well.
Once you've created such a batch file, place it in a location which exists at system startup (so better not a user-folder) and make sure only you have write permissions and SYSTEM has read/execute permissions.
In Control Panel, go to scheduled tasks, and create a new task AT SYSTEM STARTUP referring to the tempty.bat
What I'm looking to do is to virtually move the Windows/Temp folder to my D: drive somewhere as my SSD C: drive will deteriorate quickly by all these write-actions. I'm not sure how to do that yet, unfortunately.
I've figured out how to do this as well, using an NTFS Junction point:
quick how to: download junction.exe and place it in C:\Windows\System32
end all WD processes using task manager
Create D:\_Temp (or another location you want to have the WD files)
start cmd as administrator
run the command:
junction C:\Windows\Temp D:\_Temp
