  • A microwave works by bouncing microwaves around the interior. Since the shape of the container doesn’t change neither will the path that the bounced waves take. This can lead to hotspots in what you’re reheating.

    To mitigate this you have a few options:

    • move the food around in the container so that different parts pass through different hotspots over time (this is what a tray does)
    • interrupt the microwave path via a “stirrer fan” that sits below the microwave floor (this is what tray-less units use)

    Both approaches redistribute the hotspots to maximize even heating. The efficacy of either approach will come down to the specific design of either unit, but a tray-less unit can be easier to clean, and with fewer moving parts exposed to end users can be a good option for commercial/high user count settings.

    Each design accomplishes the same task of relatively even heating with few hotspots.

    Well, I try to understand why something is included. I’ve run arch for years (BTW), though my current computers are running Fedora and Debian. I won’t say I know everything about Linux or even installing it or booting it, but I do know more than I would if I just followed step by step.

    NEVER run a command you don’t know the purpose of. That being said, “sfc” stands for “System File Checker.” It is a utility that can help restore corrupted windows files. sfc /scannow checks your protected files and restores corrupted files from a local cache. The process can take some time and you MUST let it finish it’s entirely.

    In conclusion, this command is generally safe to run.
