Popular conspiracy theories according to me:
- Fluoridation of municipal water supplies is some evil government program to disperse drugs / chemicals
- Roswell was an alien UFO crash, the aliens / craft are being kept at Area 51.
- JFK was not assassinated Lee Harvey Oswald alone. He was killed by the CIA / 2nd shooter on the grassy knoll.
- Moon landing was faked
- Condensation trails (contrails) from high altitude aircraft are actually chemicals being dispersed by the government (chemtrails)
- The Earth (and only the Earth, not the Sun, moon, other planets) is a flat disc.
- Automakers have cars that run on water but they refuse to sell them to protect the oil industry.
- Global warming / climate change is a hoax to sell solar / wind / hydro power.
- Big pharma / doctors have all the cures but they’re not selling them to keep you sick & them rich
- 9/11 was an inside job (planned by George W. Bush)
- COVID-19 vaccines deposited secret microchips in the population


you can use a live USB - you run linux off a USB Thumbdrive as a test. Ubuntu would be a good place to start: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview
There’s a big ol scary warning before entering the installer and before any changes are made to your HDD/SSD, it would take a lot of mistakes in a row to somehow erase Windows by accident while using the Live USB.
