Turn off spell check by default
Of course it's set ot german and of course now I have to hunt down some setting somewhere which I dont want to do. Spellcheck should not be on by default, anyone who wants to use such a feature will actively search for it, the vast majority of users do not want it, especially not when it uses some localised setting from who knows where that is now constantly uppercasing all my stuff without me ever having this problem before.
Thanks for your feedback! I’m leaving this open for now, but in case you’re interested, here’s a link that describes how to turn this off for Windows 10: https://www.windowscentral.com/how-disable-spell-checker-windows-10
