With Windows 10, Microsoft included plenty of accessibility tools to make the operating system more accessible to people with a variety of disabilities. Go to the Ease of Access hub if you're having trouble with any aspect of Windows 10.
This can be found by going to Start > Settings > Ease of Access. You can turn on or off anything you want from here, including features like audio definitions, a magnifier, sticky keys, a high contrast option, and more. Simply select the features that will make your Windows life easier – you may need to make additional choices with some settings – and then click the Apply button.
