Why won’t the program maximize from the taskbar on Windows 11?

Some notable factors that can cause the program not to maximize from the taskbar are:

  • Viruses and malware – You can experience difficulty maximizing apps from your taskbar due to the impact of viruses and malware on the computer.
  • Faulty File Explorer – Programs not maximizing from the taskbar on Windows 11 can also occur if File Explorer isn’t working correctly. It affects the processes and tasks running in the taskbar and can cause it to be unresponsive.

As we go further into this article, we’ll discuss steps to fix the issue and get your taskbar working again.
