Windows 7: Disable Ease Of Access during login (Domain)

Disable Ease Of Access during login (Domain)

Hi everyone

See also: Ease of Access Center - Add or Remove from Logon Screen

I search a long time for a solution to disable the "Ease of Access" Button on the login screen on Windows 7 _x86 and _x64. I found a solution, but this was only for the x86 version of Windows 7. If you use this version on a _x64 machine, the login screen remains black .

Microsoft did not include the function to disable the "Ease of Access" button on the login screen and this can be very dangerous within a multi user environment. This button is hard coded within the login UI. Therefore no regkey or something else is available to disable it.

Out of this case I patched the authui.dll. This dll is responsible for the login screen and the shitty button.

I made two ready pachted dll files. One for the x86 and one for the x64 operating system of Windows 7. The version of the files are from the original Windows 7 DVD and the version Nr. of the dll's are: 6.1.7600.16385. You can use this files on every language version of Windows 7 because this files are language independent.

What was made - if you want to do it with your files by yourself:
1. Download Resource Turner (the version 1.99 can only handle x86 files!) or use Restorator 2007 Patch 2. This version can handle both x86 and x64 files.

Open it any you will see 4 entries within the UIFILE section.
3 xml files (12400, 12401, 12402) and 1 txt file (14000)

Extract within Restorator the 3 xml files and delete everything in each file starting from here:

<if id = "atom(Accessibility)">
<button
width = "38rp"
height = "28rp"
padding="rect(0,0,0,0)"
content = "resbmp(12213,2,-1,0,0,0,1)"
accname="resstr(12122)"
accdesc="resstr(12122)"
borderthickness = "rect(4rp, 2rp, 4rp, 2rp)"
background = "resbmp(12263,7,-1,0,0,1,1)"
bordercolor="gray"
borderstyle="raised"
/>
<if keyfocused = "true">
<button
borderthickness = "rect(4rp, 2rp, 4rp, 2rp)"
background = "resbmp(12259,7,-1,0,0,1,1)"
bordercolor="windowtext"
borderstyle="solid"
/>
</if>
<if mousefocused = "true">
<button
borderthickness = "rect(4rp, 2rp, 4rp, 2rp)"
background = "resbmp(12260,7,-1,0,0,1,1)"
bordercolor="windowtext"
borderstyle="solid"
/>
</if>
<if keyfocused = "true" mousefocused = "true" pressed = "false">
<button
borderthickness = "rect(4rp, 2rp, 4rp, 2rp)"
background = "resbmp(12261,7,-1,0,0,1,1)"
bordercolor="windowtext"
borderstyle="solid"
/>
</if>
<if pressed = "true">
<button
borderthickness = "rect(4rp, 2rp, 4rp, 2rp)"
background = "resbmp(12262,7,-1,0,0,1,1)"
bordercolor="windowtext"
borderstyle="sunken"
/>
</if>
</if>

until here.

<if id="atom(ToggleTabletKeyboard)"> (this line and everything below must remain)

Import the changed xml file in Restorator (for all three xml files) and save your dll.


Go to systems32 and look for your original authui.dll. Take ownership and give the Administrator full rights. Rename it to authui.original and copy your changed authui.dll into the system32 directory. Be careful. Do not mix up 32 or 64 bit files otherwise you get a black login screen. Logoff and you will see the shitty button is gone. That's it.

Here you can download the ready made files for 32 and 64 bit Windows 7:

Take the one that you need for your Windows 7 version and rename it back to authui.dll and copy it to your system32 directory. Follow the steps above to take ownership and make a backup.

I'm not responsible for any damage that you make.
Thats it - Ease of Access problem solved.

Poor MS. I'm a domain administrator and I have to make such patches to disable a shit button. Why is there not regkey or within the GPO any entry to handle such things. Shame on you!
