Microsoft has implemented a significant change by assigning the Alt+Space keyboard shortcut to its Copilot feature, which has sparked a range of user reactions. Many users express frustration over the potential disruption of their established workflows, citing that the Alt+Space shortcut has been a long-standing method for accessing system menus and certain functionalities since Windows 3. Some comments highlight the inconvenience this change poses for users who have built muscle memory around using this shortcut for different applications, such as PowerToys Run and keyboard layout switching. There's also discontent about the perceived push of Copilot onto users, with some arguing that instead of integrating AI tools smoothly, Microsoft is forcing it into users' routines despite their reluctance. A few users suggest that remapping shortcuts should be a simple solution, but the overall sentiment leans towards dissatisfaction with the company's approach to integrating AI within the operating system. This feedback indicates a challenge for Microsoft in balancing innovation with user experience and established practices.
