Dear Nishant
not really sure what you would like to achieve. But in any case: WWI.INi and some other options is the may be "right" place to check. Regarding GLM: this is more difficult.
You can not really compare behaviour of WWI in EH&S (in Winword) with other places in SAP.
Ma ybe some other persons do have better ideas to handle your issue.
