Fix the ‘1’ Key Triggering Print Screen

Have you noticed that pressing the 1 key on your keyboard unexpectedly opens the Windows screenshot tool or takes a screenshot instead of typing the number 1? This can be confusing, especially when the rest of the keyboard appears to work normally. In some cases, the problem may make the 1 key trigger Print Screen, while in other situations, pressing 1 may perform another unexpected action.

This issue is usually related to a keyboard shortcut, key remapping, keyboard driver, accessibility setting, gaming software, or a physical keyboard problem. It can also happen when a laptop’s Fn key or function-lock behavior changes the way certain keys work.

Fortunately, you do not necessarily need to replace your keyboard or reset Windows to fix the problem. You can start with simple checks and gradually move toward more advanced troubleshooting.

In this guide, you will learn how to fix the 1 key triggering Print Screen in Windows 11 and Windows 10. 

Fix the ‘1’ Key Triggering Print Screen [Complete Steps]

Before changing anything, test the keyboard in a simple application such as Notepad. Open Notepad, click inside the blank page, and press the 1 key.

If the number 1 appears normally, the problem may be related to a particular application or shortcut. If pressing 1 activates Print Screen, Snipping Tool, or another screenshot function, continue with the steps below.

Step 1: Restart Your Windows PC

The first thing you should try is a complete restart of your computer. A temporary Windows or keyboard service problem can sometimes cause an incorrect key action.

Save your work and close your open applications. Select Start, choose the Power button, and then select Restart. Wait for Windows to shut down and start again.

After the restart, open Notepad and press the 1 key several times.

If the number 1 appears normally, the problem was probably temporary. If the key still activates Print Screen, continue to the next step.

Step 2: Check Whether the Problem Happens Only in One App

The next step is to determine whether the problem affects the entire operating system or only a specific application.

Open Notepad by pressing the Windows key, typing Notepad, and selecting the application from the search results. Click inside the document and press the 1 key.

Now try the same key in another application, such as your web browser.

If 1 triggers Print Screen everywhere, the problem is likely connected to Windows, the keyboard, or keyboard software. If it happens only inside one application, check that application’s keyboard shortcuts and key mappings.

Some applications, particularly gaming tools, screen capture programs, and productivity utilities, allow users to assign custom actions to individual keys.

Step 3: Check for a Stuck Fn or Function Lock Key

If you are using a laptop, the Fn key can sometimes change how other keyboard keys behave.

Look at your keyboard for an Fn key. It is usually located near the bottom-left area of a laptop keyboard. Some keyboards also have an Fn Lock function.

Press the Fn key once and then test the 1 key again. If your keyboard has an Fn Lock shortcut, you may need to press Fn + Esc or another key combination indicated by your keyboard manufacturer.

Do not worry if your keyboard does not have an Fn Lock feature. Simply move on to the next step.

This check is particularly useful if the problem started after you accidentally pressed a combination of function keys.

Step 4: Check Your Keyboard for a Custom Key Remapping

A key remapping program may be telling Windows to treat the 1 key as Print Screen.

Check whether you have installed applications such as Microsoft PowerToys, keyboard customization software, gaming utilities, or software supplied by your keyboard manufacturer.

If you use PowerToys, open it from the Start menu and look for Keyboard Manager. Open the section that manages key remapping and check whether the 1 key has been assigned to Print Screen.

If you find such a mapping, remove it or change it back to its normal function. Save the change and test the keyboard again.

Also check any keyboard software installed by manufacturers such as Logitech, Razer, Corsair, ASUS, Acer, Lenovo, HP, or other brands. The exact names of the settings can differ between applications.

Step 5: Turn Off Keyboard Accessibility Features Temporarily

Windows includes accessibility features that change keyboard behavior. Although they are designed to help users, certain settings can sometimes cause unexpected behavior when enabled accidentally.

Open Settings by pressing Windows + I. In Windows 11, select Accessibility and then choose Keyboard. In Windows 10, you can find similar options under Ease of Access and Keyboard.

Look for features such as Sticky Keys and Filter Keys. Temporarily turn these options off if they are enabled.

Now return to Notepad and press the 1 key.

These settings normally should not turn 1 into Print Screen by themselves, but disabling them helps eliminate keyboard behavior caused by accessibility configuration.

Step 6: Disconnect and Reconnect the Keyboard

If you are using a USB keyboard, disconnect it from the computer and wait a few seconds.

Connect it to another USB port and test the 1 key again. If possible, avoid using a USB hub during this test. Connect the keyboard directly to the computer.

If you are using a wireless keyboard, turn it off and back on. Replace or recharge its batteries if necessary. If it uses a wireless receiver, disconnect and reconnect the receiver.

Now test the keyboard in Notepad.

If the key starts working correctly after reconnecting the keyboard, the problem may have been caused by a temporary connection or communication issue.

Step 7: Update or Reinstall the Keyboard Driver

A damaged or incorrectly configured keyboard driver can cause unusual keyboard behavior.

Right-click the Start button and select Device Manager. Find and expand Keyboards. You should see one or more keyboard devices listed there.

Right-click your keyboard and select Update driver. Choose the option that allows Windows to search for an available driver.

If Windows reports that the best driver is already installed, you can still try reinstalling the device.

Right-click the keyboard again and choose Uninstall device. Confirm the action if Windows asks. Then restart your computer.

Windows should detect the keyboard again after restarting and install the necessary driver automatically.

Once Windows starts, open Notepad and test the 1 key.

Step 8: Test the Keyboard With the On-Screen Keyboard

Windows includes an On-Screen Keyboard that can help determine whether the problem is caused by physical hardware.

Press Windows + Ctrl + O to open the On-Screen Keyboard. You can also search for On-Screen Keyboard from the Start menu.

Use your mouse to click the number 1 on the virtual keyboard.

If the on-screen 1 key types the number 1 normally while the physical 1 key activates Print Screen, that is a strong indication that the issue may be related to the physical keyboard or its configuration rather than the Windows text input system.

If both keyboards behave incorrectly, continue troubleshooting Windows and installed software.

Step 9: Try Another Keyboard

If you have access to another USB or wireless keyboard, connect it to your computer and test the number 1 key.

This is one of the easiest ways to determine whether you are dealing with a hardware problem.

If the second keyboard types 1 correctly, your original keyboard may have a damaged key switch, internal circuit problem, spilled liquid damage, or an incorrect hardware configuration.

If the second keyboard also causes Print Screen when you press 1, the problem is more likely related to Windows or installed software.

Step 10: Check for Recently Installed Keyboard or Screenshot Software

Think about whether the problem started after installing a new application.

Screenshot utilities, gaming applications, macro tools, keyboard managers, automation programs, and manufacturer utilities can modify keyboard behavior.

Open Settings > Apps > Installed apps in Windows 11. In Windows 10, open Settings > Apps > Apps & features.

Look for software you recently installed that can control keyboard shortcuts or screenshots. If you identify a likely application, temporarily close it or uninstall it and restart Windows.

Test the 1 key afterward.

If the problem disappears, that application was probably responsible for the key mapping.

Step 11: Perform a Clean Boot if the Problem Continues

If none of the previous steps work, a background application or service could be intercepting the 1 key.

A clean boot starts Windows with a limited set of startup programs and services. This can help identify software conflicts.

Press Windows + R, type msconfig, and press Enter. In the System Configuration window, select the Services tab.

Before changing anything, make sure you understand what you are disabling. You can select Hide all Microsoft services and then investigate the remaining third-party services.

Next, review your startup applications through Task Manager and temporarily disable unnecessary startup programs.

Restart Windows and test the 1 key.

If the key works correctly after a clean boot, gradually re-enable the disabled software until you identify the application responsible for the problem.

FAQs

Why does my 1 key take a screenshot?

If the 1 key activates Print Screen, Windows or another application may have a custom key mapping assigned to it. A keyboard utility, macro application, gaming program, or hardware configuration can cause this behavior.

Can a keyboard driver cause the 1 key to trigger Print Screen?

Yes. Although unusual, a keyboard driver or device configuration problem can contribute to unexpected key behavior. Updating or reinstalling the keyboard device through Device Manager can help.

Why does the problem happen only on my laptop?

Laptop keyboards often include an Fn key and manufacturer-specific keyboard controls. An accidental Fn or function-lock change can alter keyboard behavior.

How can I tell whether my keyboard is physically damaged?

Connect another keyboard to your computer and test the same key. If the second keyboard works normally while your original keyboard still triggers Print Screen, the original keyboard may have a hardware problem.

Will resetting Windows fix the problem?

A Windows reset is usually unnecessary for this issue. You should first check key remapping software, keyboard settings, drivers, accessibility features, and hardware. A reset should be considered only after other troubleshooting methods fail and there are broader Windows problems.

Summary

When the 1 key triggers Print Screen instead of typing the number 1, the cause is often a keyboard remapping, software conflict, Fn configuration, driver issue, or physical keyboard problem. Start with a simple restart and test the key in Notepad. Then check your Fn key, keyboard customization software, accessibility settings, keyboard connection, and driver.

The On-Screen Keyboard and a second physical keyboard are especially useful for identifying whether the problem is caused by Windows or the keyboard itself. If the issue started after installing a keyboard, gaming, macro, or screenshot utility, investigate that software as well.

For most users, there is no need to reinstall Windows. By working through these steps in order, you can usually identify what is causing the unexpected Print Screen behavior and restore the 1 key to its normal function.
