I bought a used 2011 F150 FX4. I've remote started this truck numerous times but I haven't hit the button on the dash. How do I know if I have an updated window or not? I don't care to replace a window. Hell, my defrost might not even be hooked up.

I'm thinking I should add a resistor to the circuit to reduce the amount of heat created. The question is how much. And if it shatters will Ford deny claim on the basis of the modification.
A 50W 0.25 Ohm resistor might do. Amazon sells one for about $15.
A resistor installed in series with the heating elements will reduce the current and therefore the heating in the window.
The resistor itself will necessarily get hot. So it will have to be secured to the rear of the cab (metal) to dissipate the heat.
Alternatively you can disconnect the rear window heater or install a switch.

Ford HAS NO UPDATED DESIGN. All rear defroster slider windows on trucks up through 2014 will have a high probability of exploding with the rear defroster on. Make sure to never use it - not worth the anger and frustration.

2012 FX4 Back window exploded
Taking the kid to the bus stop this morning and turned on the rear defog and about 2 seconds later a loud pop and I knew right away what had happened from reading the posts about the rear defog not working. So now I will be spending a lot of money for somebody's design flaw. Right here at Christmas, just love it.

Don't you guys have glass coverage on your insurance? Fighting with Ford seems like a huge pain and not worth my time. A simple 5 min call to my insurance and I'd have a new window. No cost to me.

Everyone has glass coverage as part of comprehensive. However, some companies don't have separate glass deductibles available (and some don't know to ask for them). Even if they do, they may have a deductible on the glass portion. A few states have zero glass deductible requirements.
