Good news about the fix - one of my big gripes with Dell laptops is they are so fussy about what order utilities are installed in and this is probably another example of that!
Control Point has three strands:
- Security - driving TPM like the fingerprint reader
- System - hooking into ACPI and running the little light sensor on the screen frame
- Connection - running the wireless connection
You can install/remove each separately.
As far as wireless goes I tend to find the Dell software works well with the integrated/Mini-PCI cards they use so leave it to manage connections - it's really whichever you feel happiest with Windows or Dell running your connection :)
