Windows 10 WHEA_UNCORRECTABLE_ERROR on first boot

Having installed the latest Windows 10 updates, my rather dated (10 year old) machine has been crashing on the first boot with the not-too-informative WHEA_UNCORRECTABLE_ERROR. Subsequently, it would remain stable till the next time the machine was shutdown and started. This led me to suspect that perhaps my machine's drivers which are no longer updated by the manufacturers are having compatibility issues with Windows 10. In particular, the Fast Startup feature may be causing this error. After disabling the feature, the error has not occurred. Hopefully, these steps will help you too:
  1. Click on the Start button.
  2. Type power.
  3. Click "Power & sleep".
  4. Click "Additional power settings".
  5. Click "Choose what the power buttons do".
  6. Click "Change settings that are currently unavailable".
  7. Uncheck "Turn on fast startup (recommended)".
