The global settings are in the Registry key HKCU\Software\Eraser\Eraser 6. Tasks are in the Task List file %LOCALAPPDATA%\Eraser 6\Task List.ersx if you are using Vista or Windows 7; the location in XP is %USERPROFILE%\Local Settings\Application Data\Eraser6\Task List.ersx.
What I don't know is whether the settings are deployable in the way you suggest. I'd be glad to know the results of your experiments.
If you have a domain network, I believe it is possible to deploy the registry settings through a GPO, and for the Task List a startup script may work. I do recognise that enterprise deployments are a little sticky at the moment, but I don't really know what would be needed for larger deployments (e.g. like yours) as my network only has about 10 computers (it's a personal one, not a corporate one, but with AD and all)
Yes, both of the fixes stated above are working, thank you very much! I have created a batch file that does both tasks and have compiled it into a self extracting exe so we can deploy it and just tell it to run.
The batch lines are as follows:
::Edit of the Registy for the ClearcompletedTasks value.
REG ADD "HKCU\Software\Eraser\Eraser 6\3460478d-ed1b-4ecc-96c9-2ca0e8500557" /v ClearCompletedTasks /t REG_DWORD /d 0 >> C:\eraserfixlog.txt /f
::Copying of the Task List to the Application Data
COPY /Y "C:\ERASERFIX\Task List.ersx" "C:\DOCUMENTS AND SETTINGS\ADMINISTRATOR\LOCAL SETTINGS\APPLICATION DATA\ERASER 6\" >> C:\eraserfixlog.txt
