Hi, my name is Kelly, and I'm an independent consultant and I'm here to help.
It sounds like you are experiencing an issue with the way windows are being restored after minimizing and maximizing them in Windows 11. Here are some steps you can try to fix this issue:
Use the Snap feature: Instead of manually resizing the windows every time, you can use the Snap feature in Windows 11. This allows you to snap windows to specific positions on the screen, making it easy to quickly organize multiple windows. To use Snap, simply drag a window to the left or right edge of the screen, and it will automatically snap to that position. You can also use the Windows key + left or right arrow keys to snap a window to the corresponding edge of the screen.
Disable the "Snap windows" feature: If you find that the Snap feature is interfering with your window sizes, you can disable it. Go to Settings > System > Multitasking, and turn off the "Snap windows" feature. This will allow you to manually resize windows without them automatically snapping to specific positions.
Use keyboard shortcuts: You can use keyboard shortcuts to quickly minimize and maximize windows. Press the Windows key + down arrow to minimize a window, and press the Windows key + up arrow to maximize it again. This may help reduce the amount of resizing you need to do.
Use third-party software: If none of the above solutions work, you can try using third-party software that allows you to customize window sizes and positions. Examples include WindowManager, AquaSnap, and TileTabs. These programs may offer more advanced features for managing multiple windows on your screen.
Hopefully, one of these solutions will help you maintain your window sizes when minimizing and maximizing screens in Windows 11.
