Adjusting from Mac to Windows 11: Resizing Windows and File Explorer Freezes

Hey everyone! I'm a Mac user who recently switched to Windows 11, and I'm running into a couple of frustrating issues. First, resizing application windows feels way too tricky. It seems like I only have about 2 pixels of space to hit the right spot for the "resize cursor." It usually takes me around 5-10 seconds to get it right, which is annoying.

The second issue is with File Explorer. Every time I try to move or delete files, about 50% of the time a progress window pops up, and it takes anywhere from 10 to 30 seconds to finish the action. I've had this problem on my old PC, and thought a new one would solve it, but I'm still seeing the same behavior. Is this just how Windows operates? I shut my PC down regularly, and I've only got a few apps open at a time, plus my SSD is only about half full. Here are my specs: Windows 11 Pro, Intel Core i9-13900KF, RTX 4090, 64GB DDR5 RAM, 2TB SSD. I'd love any tips you have!
