Is the osx search performing so much better on your end? If so, in results or speed? Because for me, both osx and windows searches leave me annoyed anytime I try to use them, it's so bad that I usually prefer to use CLI tools on both platforms ...
Or were you just saying it cuz it's funny?
I occasionally get the multicolor disk spinner which locks all UI interactions for a few seconds (10-30s) until it unfreezes and works as before again...
Haven't been able to figure out the exact cause for it, feels very random.
(My guess is that the Windows issue is something similar? but I have no experience with it, so don't know if it can be fixed in a similar way)
