The Function Keys (F1 to F12) on the Windows keyboard have specifically assigned roles. For example, F1 opens the help page of any application you’re currently on. This is useful in many situations. However, you may want to disable it for some reason.
The Windows operating system doesn’t provide a method to disable the F1 key, but I’ll show you some tweaks to get it done. In this article, you’ll learn how to disable the F1 key on your keyboard temporarily and how to re-enable the key using several methods.
Disable F1 Help key on the keyboard
Read this section and follow the guides closely because we’ll modify the Windows system’s delicate components, such as the Registry Editor. Here are the methods we’ll explore in this guide:
- Disable the F1 key using AutoHotkey.
- Disable the F1 key from the Windows Registry.
- Re-map the F1 key using SharpKeys.
Let’s take a look at the steps involved in the above solutions for disabling the F1 key.
1] Disable the F1 key using AutoHotkey
AutoHotkey is a free, lightweight Windows tool that lets you create scripts for carrying out simple and complex tasks. With AutoHotkey, you can build auto-clickers, form builders, macros, etc.
This scripting tool also enables you to remap keys and create hotkeys. Hence, it provides an easy way to disable the F1 key on your PC. To download AutoHotkey, visit autohotkey.com or download it from this direct link.
Double-click the downloaded file and complete the installation following the on-screen instructions. After installing AutoHotkey, run it.
Minimize the application and right-click on your Windows desktop. Go to New > AutoHotkey script from the context menu. You can rename the new script to whatever you like, but leave the extension as .ahk.
Next, right-click on the new script and select Edit script. Enter the following line into the script at the end of the text already in the file:
After entering the line, hit CTRL +S or click on the File menu and select Save. You can now close the script window. Finally, right-click on the script on your desktop and select Run script to disable the F1 key.
With the script now running, pressing F1 will do nothing. To disable or pause/resume the script, click on the little arrow on your taskbar and right-click on the AutoHotkey icon.
Here, you’ll find options to reload, edit, suspend, pause, or stop the script.
2] Disable the F1 key from the Windows Registry
Press the Windows key and search for registry in the Start menu. Right-click on Registry Editor and choose to Run as an administrator.
Navigate to the following registry key:
TIP: You can copy the above path and paste it into the Registry Editor’s address bar.
Right-click on the Scancode Map key and change the value data to:
00000000 00000000 02000000 00003B00 00000000
Click OK to save the settings and close the Registry Editor.
If this Registry Editor tweak doesn’t work as planned or you want your F1 key back, you can always return to the key and change the value data back to:
00000000 00000000 00000000 00000000 00000000
3] Re-map the F1 key using SharpKeys
SharpKeys is another Windows tool, but unlike AutoHotkeys, SharpKeys is solely for remapping Windows keys. It’s easy to use because the keys are already laid out on the interface, and you do no scripting.
To use this program, download it from Github first and launch it from the Start Menu. Click on the Add button from the home interface.
Click on the Type Key button on the left, under Map this key, and press the F1 key on your keyboard. SharpKeys will detect the Function: F1 (00_3B) key pressed.
Hit OK on the popup to close it.
Alternatively, you could locate the Function: F1 (00_3B) item directly from the left-hand list.
Click on the topmost item, Turn Key Off (00_00), on the list in the right-hand box.
Hit the OK button.
Finally, click on the Write to Registry button and restart your computer.
On the restart, you’ll discover that you’ve successfully disabled the F1 key on your keyboard.
To re-enable the key, open SharpKeys, delete the entry you created, and hit Write to Registry.
