I recently had a new issue with the Defender: there are 2 apps I use that can delete files from disk, one is a mp3 player (foobar2000), the other is a video player (PotPlayer), both have a hotkey to "delete the current file being played". I've been doing it for years, but recently when I do it, the app will freeze for 5 seconds, meanwhile the CPU usage of window defender will shoot up in Task Manager. I tried to tweak all kinds of different settings in the Defender, and couldn't find a fix.

So on the one hand I want to validate and recognize both that you're having this problem and that finding a real live person who might be able to help you with it totally, very reasonably, evokes a "hey, can I tell you my problem?" response. I don't want to minimize that, but I do want to (gently, good-naturedly) say that I think it's kinda funny. As someone who once worked at a big tech company I think it's totally hilarious how telling people "I work on X product at Y company" totally evokes this sort of response. Tell enough people where you work and you'll see some non-zero percentage of people respond like this. Like, when I was talking with a mover who was unloading my stuff and he asked "So, what brings to you these parts?" and I told him his first response was "Really? Y'know, I've got that software and it doesn't work for me under these very specific conditions. Why is that?" (At the time I think I mumbled something about "I don't know". In retrospect I was moving to start work there so I realistically couldn't have known yet). So - I hope you get your problem sorted out, thank you for giving me the opportunity to talk about this, and I think I'm gonna go chase some kids off my lawn now :)

  Wait until you hear what happens when you say you’re a doctor, electrician, carpenter, builder, mechanic…

    As a mechanic in a previous career, I can verify that. The only answer I ever gave was: "Sure I can look at that, bring it into the shop, we're open eight to five Monday through Friday, eight to two on Saturday, and open until eight PM on Wednesday and Thursday, but only for drop off, pick up, and tire changes."

  This is why those t-shirts exist that say "NO I will not fix your printer"...

  The problem is that quite often asking some random person that works on X at Y company to take pity on you and look into your problem is more effective than the official support channels because they are so useless that they may as well not exist.

I have no idea and I don't work on that bit but there are lots of troubleshooting guides on "what to do if Defender is slow in situation X" in our docs - in 99% of cases it's interference (another program scanning) or specific programs acting in ways that trigger scanning often. In all cases there are workarounds - I'm not using the Windows version (I'm on a mac) but when I had a performance issue it ended up being a script that created and deleted thousands of files quickly and tweaking it was fairly simple.

This is a pretty drastic fix, but if you don't really care about the video and audio files, and you're willing to lower security a bit, you can exclude the library locations from defender. I've done this with a couple of folders so defender doesn't scan executables from local compilation of code. Just remember to scan things when you download or copy from friends.
