I'm in a rare bizarre situation and this is a desperate attempt to not buy any new hardware.
Basically, I need a minimalist, no BS, no autoupdate, no auto-turn-back-bad-settings-weekly version of windows specifically for the purpose of running windows occasionally and only connecting my phone to it to run this one specific application https://www.samsung.com/uk/apps/samsung-dex/
Scrcpy does not trigger Samsung Dex (or Android Desktop for non-Samsung devices), otherwise I'd just use that on my Garuda MATE Linux installation. I will be tinking with wine later but I doubt it will work.
Any option that involves spending money will probably not be worth it because if I am spending money on this, I'd rather get a portable monitor (they're not that expensive).
Know of any specifically good windows ISO or what the gold standard of keeping a rogue OS like windows in check?
I'd like some LLM features centered around "here is my organized folder of documents for context" but without paying $20/month or buying a $2,000 GPU or giving all of my data to Google/Microsoft. I couldn't find anything that actually worked even if I did pay money or give my data to Google/Microsoft. Ignoring even the folder thing, I remember asking Claude to summarize a novel I'm writing and it kept mixing character's with details that unambiguously only applied to other characters.
