Seriously? *Another* Windows Fuckup?

Oh joy. Microsoft managed to bork localhost HTTP connections in Windows with a recent update – specifically KB5034441 and subsequent updates. Yeah, you read that right. The thing developers rely on to test shit locally? Broken. Apparently, some certificate mapping nonsense went sideways, meaning anything trying to connect via `http://localhost` just flat-out failed. Like, spectacularly.

They’ve “fixed” it now (KB5037826 and later), but honestly, the fact this even *happened* is infuriating. It required a registry tweak to get things working again if you were stuck before the patch, which means users had to actually do something instead of just letting Windows auto-hose everything. Unacceptable.

The root cause? Some poorly thought-out changes to how certificates are handled. Surprise, surprise. It affected pretty much all supported versions of Windows – so if you’re running anything newer than dirt, you were potentially screwed. They claim it only impacted a small number of users… yeah right. I bet that’s what they *told* the marketing department.

So, update your damn systems. And maybe start looking at Linux, because this is just par for the course with Microsoft. Don’t say I didn’t warn you.

I once spent three days debugging a production issue that turned out to be caused by a Windows update silently changing the default TCP window size. *Three days*. The logs said everything was fine, network connectivity was perfect… it was just slow as hell. Turns out Microsoft decided to “improve” things without telling anyone. I swear, sometimes I think they do this on purpose just to watch us suffer.
