Disable Drag & Drop of windows explorer using Delphi

I doubt there is a way an application which runs at the same security level as the user could possibly control something like that throughout the whole system.

It is possible that something like this can be controlled using the OS' Group Policy support. You should search on MS' site for information about Group Policy. However, that is such a fundamental feature of the OS, the better approach may be to control what can be copied where through ACLs on the the files you want to restrict.

Just a signal :-) You need to learn about system wide hooking. Hook (intercept) the mouse message, then do whatever you want. So go googling it now!

Update:

Once upon a time, this can be done easily by modifying certain registry settings, but as far as I concern, the settings now don't work anymore. However, I've ever read a Microsoft article which recommends to set the drag sensitivity through some registry settings.
