I get a dialogue from Microsoft defender smart screen that looks mighty similar to this whenever I've done a clean install of Oobabooga's Text Generation WebUI (for running local Large Language Models) with it basically going "are you really sure about running that" for an incredibly niche piece of software. OP seems to have lost the plot if you ask me, because quite frankly Microsoft will only be able to exert the level of influence over our machine if it were in the cloud running on their servers. and even then, they aren't going to kill off the local windows install because funnily enough, the internet ain't that available.
