Difficulty in Customizing Settings on Windows 10 computer

I'm having trouble customizing settings on my Windows 10 computer, as many options seem locked or unresponsive, making it difficult to personalize the system to my preferences. Despite trying different methods, I can't access or modify certain features like the taskbar, appearance, or privacy settings, which hampers my ability to tailor the device to my needs. I need guidance on how to resolve these restrictions and gain full control over my Windows 10 customization options.
