Blocking Processes

Is there a was that I can block certain windows processes from running. I want to know if there is a general way to do this for any process.

Try looking in control panel "administrative tools"

EDIT:

It would help if you told us what you were trying to do.

1. Do you want to block certain users/groups from running certain processes?

2. Do you want to permanently block certain processes?

3. Do you want to force a manual launch of certain processes?

4. Do you want the system to ask permission for the launch?

Please take a look at this:

OK, it is supposed to be a security solution, but if it does what you want as well, why not use it? There is a free and a commercial version.

Also:

1. What version(s) of Windows?
2. Workstations only?
3. What sort of processes?.............remember, Windows breaks very easily.
