This is my favorite reg tweak. If you use Task Manager as much as I do, then you will appreciate having it setup exactly the way you want it, all based on this registry setting.

First, get Task Manager configured just the way you like it. Add or remove columns in the Processes tab, change the Update Speed if desired, etc. Since this registry setting also saves the position of the Task Manager on the screen (as well as the width and height) I highly recommend that you adjust these settings as well. For the purpose of this setting, I move the Task Manager window close to the upper left of the screen so that it is visible on smaller screens. After I'm done retrieving this reg setting, I move and resize the window back to fit my large screen.

--------------------------------------------------------
Listed below is the Registry key that you need to save. PLEASE NOTE THAT THE SETTINGS BELOW (for the Preferences key) REFLECT MY OWN SETTINGS. I HIGHLY ADVISE YOU TO USE YOUR OWN SETTING FROM YOUR REGISTRY, AS I DO NOT KNOW WHAT MAY HAPPEN IF YOU USE THIS SETTING FROM MY REGISTRY.
Of course, I don't expect anything bad would happen, but ya never know....

Now find this key in the Registry and export it to a file for inclusion in your unattended CD.

This is how I use TM: I have enabled the option to "Hide when Minimized". I like my TM always running in the system tray, so I have added Task Manager to the Startup folder in the Startup menu (All Programs >>> Startup). Next, I edit the properties for this Task Manager shortcut and set the Run box to "Minimized". This causes Task Manager to launch every time I boot, and it stays in the system tray, not on the task bar.

Please note that this key only affects the current user; you can't set it at the LOCAL_MACHINE level or for the .DEFAULT user hive under HKEY_USERS. This setting (unfortunately) can only be set under HKEY_CURRENT_USER.
