Absolutely, you can acheive a Windows 11-like appearance on Windows 10 with some tweaks and third-party software, though caution is always advisable to avoid compromising system stability and security.
For the centered taskbar and new start menu design, I recommend tools like "StartIsBack" or "TaskbarX". These provide customization options that closely mimic the Windows 11 interface and are well-known for their reliability and minimal impact on system performance.
For rounded corners, you might want to check out "WindowBlinds" which allows for extensive customization of window shapes and other UI elements. It's quite robust, but make sure to exhaust it in a controlled setting initially to ensure compatibility with your specific system configuration.
Always ensure any software you install is from a reputable source and regularly updated. Additionally, creating a system restore point before applying such changes can provide an extra layer of security by letting you revert your system back to its original state if needed.
By taking these precautions, you should be able to safely enjoy a fresh UI experience similar to Windows 11 on your Windows 10 machine!
