Note:This CAN NOT and WILL NOT cause any harm to the victim's computer. If you encounter any troubles, just restart the computer. Any damage caused as a result of trying this out is neither my FAULT nor my RESPONSIBILITY. Any damage caused is your fault, due to incorrectly following these steps (and your computer can befall harm if you exit certain system-crucial processes). This process is harmless.
Step 1: Open Windows Task Manager
1. On MOST Windows XP versions (and previous versions of Windows), press ctrl-alt-delete to open task manager.
*On some computers, the administrator may have changed that function to leave the desktop, and open a window that has a couple different functions, such as shutting down the computer, simply select the open task manager button, or, if this doesn't work for you try the Vista steps.
2. On ALL Windows Vista versions, press ctrl-shift-esc to open task manager. (You can also use ctrl-alt-delete and then select open task manager.)
**Important Note: On some systems, the administrator may have disabled Windows task manager. I have found that this isn't the case on most systems (the only example I can think of are the public library computers, locked down to browsing the library's online database). If this IS the case, you will get a "the administrator has disable windows task manager" error.
3. Now that you have Windows task manager open, navigate to the "processes" tab, as shown in the picture.
