If “entering the keyboard twice” is repeated, it is better to narrow down the switch chattering and repeat speed settings rather than changing several settings at once. Compare with other ports and other PCs to distinguish between problems with the keyboard itself and problems with Windows input settings and drivers.

After these steps, see if the “Keyboard Typing Twice” symptom decreases or disappears. If there is no change, the possibility of switch chattering is also checked in the next step.
Distinguish whether it is a Windows input issue or a physical keyboard issue.
Some keystroke errors may be due to accessibility, language, or repeat rate settings.
Outdated or corrupted keyboard/HID drivers may be causing the symptom.
If only a specific key fails or is pressed twice, there is a high possibility of a switch/membrane problem.
We've put together a list of things we frequently check regarding this issue.

When troubleshooting no keyboard input at all, it is important to rule out the causes one at a time. Based on the “Keyboard not working” symptom, check the USB/Bluetooth connection and driver and proceed to the next step. Compare with other ports and other PCs to distinguish between problems with the keyboard itself and problems with Windows input settings and drivers.
If “specific key does not work” repeatedly, it is better to narrow the scope to key switch/membrane issues, key mapping, and language settings rather than changing multiple settings at once. Compare with other ports and other PCs to distinguish between problems with the keyboard itself and problems with Windows input settings and drivers.
This guide is designed to categorize switch wear and double-click speed setting items in a safe order in “mouse double-click” situations. Divide the problem into the mouse hardware and PC side by testing sensors, batteries, wireless connections, and other ports.
When troubleshooting a USB device that keeps connecting and disconnecting, it is important to rule out the causes one at a time. Based on the “USB keeps disconnecting” symptom, check USB power management, hub/cable, and proceed to the next step. Cross-test devices, cables, and USB ports and check for power management and driver issues.
