I wouldn’t bother with LTSC. Just install Enterprise/Education and disable feature updates.

If you do connect to a network. Shift+F10 again and

netsh wlan delete profile name=*WiFi SSID*

And reboot.

I guess it wouldn’t make sense to measure energy used by gas-powered appliances in Wh since they’re not rated in Watts. Still, measuring volume and then converting to energy seems unnecessarily complicated.

Joules (J) are the official unit of energy. 1W=1J/s. That means 1Wh=3600J or that 1J is kinda like “1 Watt second”. You’re right that Wh is easier since everything is rated in Watts and it would be insane to measure energy consumption by seconds. Imagine getting your electric bill and it says you’ve used 3,157,200,000J.
