Hi,
Thank you for contacting Microsoft community.
As you have stated that whenever you turn on computer the filter and sticky keys are automatically turned on and you are able not disable it when you boot your computer.
I would like to suggest few troubleshooting steps.
- Click Start
- Type Control Panel and open it.
- Click the “Ease of Access” heading.
- Click “Change how your keyboard works”.
- Remove the check mark from the box next to “Turn on Filter Keys”.
- Click the blue “Set up Filter Keys” link.
- Underneath “Keyboard shortcut”
- Remove the check mark from the box next to “Turn on Filter Keys when right SHIFT is pressed for 8 seconds”.
- Click OK twice.
