A control panel that has only the functions that I need. How do I create one?
I've seen this method before for Vista. I've reviewed it, and there is no reason it can't work in Windows 7 as well.
It just involves creating a new folder (your custom control panel), then filling it with shortcuts that open the control panels you want via command line (for example, try "control desk.cpl" in a command window, and you'll get the display settings).
Depending on what you want in your custom panel, many of the system utilities are run via snap-ins to the MMC (Microsoft Management Console).
You can author your own custom MMC: start-->run-->'mmc', add snap-ins you want, and then save it for future use.
Here's some info from MS on authoring your own MMC. It's more straight-forward than they make it out to be (as usual :) ).
Just create a folder and drag &drop the needed functions from the control panel to it...
You could also use the "Master Control Panel" aka "God Mode":
It's a CLSID (or Windows Class Identifiers) folder and you will find 278 controls in it.
And you could also use directly some other CLSID folders:
Additionally, to simplify the creation of these folders: GodMode Creator
