End Google Ads 201810 - BS.net 01 --> My problem is similar to the one described here:

http://www-01.ibm.com/support/docvie...id=swg21230924

In our application we have DLL that is used to write information to Event
Log. Problem is when I need uninstall/upgrade our application this DLL is
often locked and it requires computer reboot which is undesirable.

I know there is a way to unlock/delete this file because this is what
Unlocker application does (http://ccollomb.free.fr/unlocker/)

Does anyone have any ideas on how this is achieved using Windows API?
