Filter Keys is a feature in Windows that helps to reduce accidental keystrokes by making the keyboard ignore brief or repeated key presses. This can be helpful for people with hand tremors or other conditions that make it difficult to type accurately.
Filter Keys can be turned off in the Windows Control Panel. To do this, open the Control Panel and go to the Ease of Access Center. Under the “Keyboard” section, click on “Make the keyboard easier to use.” In the “Filter Keys” section, uncheck the box next to “Turn on Filter Keys.” Click on “OK” to save your changes.
