1] Clean Keyboard

The first step you should do is check the physical condition of your keyboard. Check for dust, dirt, or impact on the lock switch or buttons. If there is, try cleaning it in the following way:

1. Unplug the keyboard from its desktop PC.
2. Place the keyboard upside down. If you are using a laptop, place the laptop upside down. This makes the dirt on the keyboard can fall off when cleaned.
3. Press the keyboard and pat the back of the keyboard/laptop. The next way to clean the keyboard is to press the keyboard keys. This will help the dirt on the keyboard can come out easily. To clean quite difficult dirt on the keyboard, you can gently pat the back of the laptop. Pat gently so as not to damage your beloved Laptop.
4. Use a brush or makeup brush. Remove any remaining dirt or dust between the laptop keyboard with a soft brush or makeup brush. The brush has a small and soft brush bristle so that it can reach the gaps in the keyboard keys. Make sure every part of the button is well brushed.
5. Sterilization with alcohol swab. This one step is quite important. Cleaning a laptop keyboard with an alcohol swab can kill bacteria and viruses, which certainly cannot be eradicated with a brush and vacuum cleaner. 
6. Use a special keyboard vacuum cleaner. A special keyboard vacuum cleaner has a small size. This vacuum cleaner can work with electrical power from USB or batteries. This vacuum cleaner can vacuum between the remaining keyboards during the drying process.

2] Adjust keyboard settings

Repetition is a feature that allows you to type double characters repeatedly by pressing certain keys.

If repetition is not to your liking, then it can cause the keyboard to type double letters. To set up a recurrence, you can follow these steps:

1. On the Start Menu, type “keyboard” to open the keyboard properties.
2. Then in the “Character repeat” section, you will find the option “Repeat delay”. Move the slider from Short to Long to change the pause between double characters.
3. Also set the “Repeat rate” option to get the appropriate setting, which is close to Slow.
4. Click the Apply button and OK button to save the changes.

3] Add settings to the Windows registry

Changing the registry is a risky step if done the wrong way. Therefore, make sure you follow these steps carefully.

For added protection, save the registry before you change it. Then, you can restore the registry if there is a problem.

1. Press the keyboard keys (WIN + R) to open the “Run” dialog box. Type “regedit” and press the Enter key.
2. In the “Registry Editor” window that opens, navigate to :

3. Next on the right-side panel, double-click on “AutoRepeatDelay”. Change the Value data to “500”, and then click OK.
4. Change the Value data from “AutoRepeatRate” to “50” and save the changes.
5. Next, change the Value data from “BounceTime” to “35” and click OK.
6. Restart the computer to make the changes take effect.

A driver is a program that connects hardware with the operating system. If your keyboard driver is corrupted or outdated, then it could cause the keyboard to type double letters. To update the keyboard driver, you can follow these steps:

1. Press the keyboard keys (WIN + X) and select the “Device Manager” option.
2. Expand on the “Keyboard” section.
3. Right-click on the keyboard driver you are using and select “Update driver”. Then follow the on-screen instructions to find and download the latest driver.
