Disable F1 in Windows Explorer

Help center logoMany power Windows XP users who frequent the F2 key for renaming files seem to have the same problem hitting the F1 key every now and then, bringing up the rather slow Windows Help and Support Center. Since there doesn't seem to be an official registry-based fix without disabling F1 completely or running a background process to trap the key, I had to figure out a hack. Here's my solution, and I think it's pretty clean.

When you press F1 in Windows Explorer, an EXE called "helpctr.exe" is run. This makes it relatively easy to get rid of this behavior, by replacing it with a dummy executable that does nothing.

Of course, if your copy of Windows is somewhere other than C:\Windows, replace any references with the correct directory.

  • First, download the dummy EXE to C:\Windows\
  • Run the Registry Editor: go to Start, Run, and type:
  • Navigate the tree on the left to the following location:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\HELPCTR.EXE
  • On the right side, double-click the word "(Default)" in the list
  • Change the value in the text box to:
  • Click OK and close the registry editor

To test the fix, just visit My Computer and press F1. Nothing should happen!

This solution seems to have no negative impact on other programs' Help systems, since regular Windows Help files don't use the Help Center.

Thanks to "Shaun" on my guestbook for suggesting this newer, cleaner method.

thanks for the tip. my one problem.. dummy.exe? as in, if you download & run this you're a dummy? I know, it's probably completely trustworthy, but still, would be a great place to hide a virus. The trick works just as well if you use some built-in system process that terminates instantly when given no arguments; for instance I use "svchost.exe" in place of "C:\Windows\Dummy.exe" (another pro-laziness note - you don't have to give it a full path because the system defaults to looking for programs in the system32 folder, which is where svchost.exe and other such stuff hides. something handy to keep in mind for adding command-line tools if you're a fan of those.)

I know exactly what you mean. I figured that the 4kb file size should be a pretty good indicator that it's safe, but it's not foolproof (how much code does it take to wipe out the MBR?).

Another good replacement executable is "rundll32", which also does nothing if you give it no parameters. I just worry that something will eventually try to pass arguments to helpctr.exe and you'll get unpredictable results with built-in EXEs.

My dummy.exe was written in VB5 and compressed with UPX so that it's as small as possible. I'll try to post a C++ version of my dummy file soon, along with its source code so that people can be more confident.

what if you want to disable the f1 key for all programs, what should you do? Mine is stuck and won't quit popping up the help window for every other program now even with the download of dummy.exe

why not just rename the files, making the original something like helpctr_old.exe? i don't see the need to go messing with the registry.
  • Ethan
  • October 26, 2008
  • 1:02 am
m: Renaming the files would work fine, but that's not easily done because helpctr.exe is a protected binary, so Windows won't let you modify it. My instructions used to guide users through that exact process, but this method is decidedly easier.

I usually just set mine to

it pops up and auto closes, but returns you to where you were in explorer...

It is built in to windows, so no downloading, does not use much memory.


it is html help, if not args it opens and closes.

just want to share somethin.. disabling F1 key in Excel 2007 coz me either often using F2 to edit formulas/value and so i got this website. doiing the same technique.

go to Start run.. type in regedit

find for this string in the registry "C:\\Program Files\\Microsoft Office\\Office12\\CLVIEW.EXE" (without qoutes) then change with C:\Windows\dummy.exe or wherever location you like.

it's good to backup your registry first:

mine is here
Windows Registry Editor Version 5.00

"00002109030000000000000000F01FEC"="C:\\Program Files\\Microsoft Office\\Office12\\CLVIEW.EXE"<br/>
That's it! Goodl uck

This is awesome! Works a charm, thanks...
I just thought of something...

Wouldn't it be possible to change the F1 key to function the same way as F2?

That way, if you accidentally hit F1 when renaming, it's no big deal because you still get the rename function?? That's what I would do if I knew how, LOL!

In addition to my first post on "disabling F1 key in Excel 2007"

To make your life easier than digging into registry settings.

Just simply go browse to your installation directory of MS Office 2007 (eg. C:\Program Files\Microsoft Office\Office12)

find the culprit CLVIEW.EXE and rename it to somethin like CLIVEW.EXE_

That's it !

Anyone found a way to stop this in Vista?

  • Dave T

I find that the built-in help is usually less useful than typing my problem into google, so the F1 key is my last line of defence. I press it more times accidentally than intentionally.

A non-software solution is to remove the f1 key from the keyboard. That way, it can't be pressed. I've just done this, and it took me 1 minute. I didn't need a registry editor, neither did I have to download any dummy.exe viruses. My solution works in all applications, and I can revert back to the former behaviour by putting the key back in!

However, you should use linux also, if you are so worried about viruses ^_^. I just simply coded my own exe. It took me an entire 10 seconds to write and compile, and I wrote it in C.

  • Ethan
  • February 20, 2009
  • 11:39 pm
Max - you might look to see if you can figure out what's running whenever you hit F1 and disable that program. Excel 2000 is pretty old, though, so it might just be something as simple as winhelp.exe ... which you probably don't want to disable completely.

Boy, did I go browse, find, rename, and *poof* the fluorescent lights opened up into blue skies and the ventilation ducts grew branches and leaves and started singing like Bala Murali Krishna.

No more F1 "help" hassles! Thanks, ffphguy and Ethan and everyone else who made this magic moment possible!
That is good solution but it's better replace F1's mission for rename. Is it impossible? With that way when you hit f2 it renames and when you hit f1 it renames too.
Note: sorry for my bad english.

I presume these are just false positives.
  • Ethan
  • August 22, 2009
  • 5:37 pm
I imagine those false positives are based on the fact that I compressed the binary with UPX. I imagine that's done in the case of some spyware apps to hide the strings used in the file, making them harder to recognize as spyware ... thus, spyware checkers will flag UPX compression. I just did that to make the EXE as small as possible. If you're uncomfortable with my dummy EXE, you can do what the other comments have suggested and find a random EXE in the Windows dir that does nothing visible.

To disable F1 key, just download Sharp Keys

on section "Map this key" choose "Function F1",
on "To this key" section choose "Turn Key Off"

you're done!

Your dummy.exe results in the following dialog:

Open File - Security Warning
The publisher could not be verified. Are you sure you want to run this software?
Name: dummy.exe
Publisher: Unknown Publisher
Type: Application

I'd prefer a dummy executable that doesn't trigger a security warning...
  • Ethan
  • September 16, 2009
  • 6:16 pm
Any EXE that's unsigned will show that warning. I can't get my EXE signed unless I pay for a signing certificate, which is a bit excessive for this case. If you're uncomfortable with my dummy.exe, there are plenty of inert EXEs in the Windows directory that you can point to instead.

This is also a great trick if you have an administrator who thinks you just have to have a completely worthless program using up resources and won't take no for an answer. I was specifically looking for a dummy program to replace the executable since every attempt to delete or uninstall has failed. They always put it back. This time I think I beat 'em. Thanks!

I was wondering if it is possible to disable to F1 key completely. Because now I accidentally press it while a SQL Server 2008 or Visual Studio 2008 window is active, and I don't know why, but then this little window pops up that says something like "Building help document..." or something, and that shit sometimes takes ages. I want to completely "remove" the F1 key from existence...on my computer :P

when starting up your computer press f10 to go into bios mode. then go over to system configuration and youll see something that says action keys enabled or function keys enabled, i already forget. anyways just disable it and presto!

MS Office: renaming CLVIEW.EXE worked! Thanks ffphguy.

Thanks Ethan for your work and sharing this information with us. It's much appreciated. Since this method doesn't work on Win7, here's an alternative.

Windows 7: I just tried Unlocker and it worked perfect and all I did was move the files. The Help Center files are normally locked and unmovable, but if you can move them out of C:\Windows\ Help Center will not be able to execute.
-Download Unlocker 1.9.0 Portable by Cedrick Collomb (no install required).
-Run your version (x86 or x64) and locate the files HelpPane.exe and winhlp32.exe in C:\Windows\.
-In the next pane choose "Move" from the drop down menu on the left and navigate to a backup folder.
-You may have to repeat for each file.
-You're done!
**To undo this, simply move the two files back to C:\Windows\.

fortunately you cant rename important system files (unless you take ownership with an administrative account), else you would create a vulnerability!
users could just open for example, pictures from a network location in Paint and then press F1 and it would load a 'helppane.exe' file from this network location. very bright solution loool. be ware with what you read and do people!

Unsurprisingly, they made the help menu even worse in windows 10. Now instead of having the help menu appear, it brings up a bing search in your web browser, while locking down the explorer window you were using.

Absolutely amazing the lack of thought they put into these updates.
Please wait ...
