Windows defender makes Windows 10 absolutely impossible to use on slow (non-SSD) drives. That would be fine if there was an easy way to disable it, but it's literally impossible without digging through guides online. It's insanity that this is allowed.
You might be interested in OOSU10 (https://www.oo-software.com/en/shutup10) which has options to disable just about everything you can think of, including Defender.
I've started using OOSU10 on all my Windows installs as well as Windows10Debloater. It makes a performance difference on resource constrained devices and for other devices I just like a cleaner Windows install.
I'd say it is easy enough, just paste some random scary command from a quick Google search into the shell. Or maybe my expectations are too low. It is not like I could have known how to disable the insanely stupid ApplePressAndHold thing on macOS without searching online...
The problem is the average person wouldn't know what a shell is in the first place, and those are the ones with the least powerful machines that suffer the most from this. They shouldn't have to go through a process that has the possibility of ruining their machine just to get it to work reliably.
