If you are hesitant to execute code from the internet (you always *should* consider very carefully what code you allow and don't allow to run on your machine, since the internet is a crazy phenomenon with malicious code and strange individuals all over the place) you can also look at the method described below in order to enable task manager.

Of course, if your computer is part of a company network, your network administrator may have decided to disable the windows task manager on network computers. If that happens to be the case, your best option would of course be to contact your network administrator and ask him or her about the "task manager disabled by administrator" dialog.

On the other hand, if you are working on a home computer, there's a good chance that you have become victim of a virus or malware infection when you find your task manager grayed out or disabled.

There are a number of viruses and spyware infections that work their way into the windows registry and disable task manager in order to complicate their removal.

Some spyware or virus infections are known to spawn processes that eat up nearly 100% of your computer processing capabilities (cpu time) causing your computer to become terribly slow. Checking the number of processes and their cpu utilization is one of the first diagnostic tasks that a system administrator might carry out in order to solve the computer slowness, that's why those malware infections rule out task manager consultation.

Using one of the techniques described in this article will allow you to enable task manager, but if your computer is infected with some virus or malware program, you will also need to perform a virus scan or check your internet security software.
