Did not work

Hey, I followed the steps above precisely and it did not work. It was strange, it comes back with explorer, but ctrl+alt+del does not work and there is no "shut down" text when I click my start orb. Then after about 15-20 seconds I just get a black screen. It continues to be a black screen when I reboot. Any idea why it is not working?

sounds like what happened to me the first time, did you copy the code into notepad or just change it in the Resource Hacker?

I have followed this method plenty of times on windows 7 x64, but doesn't work only black screen with just the cursor, i have changed the SysWow64 authui.dll as well so it matches the same as the system32 authui.dll, however still the black screen, hmmm. Worked straight away when i did this method on windows 32-bit though.

Any able to get this customization to work with x64?

I just got the black screen whilst trying to do this change and there's nothing I can do to reverse the black screen, I've got no task manager appearing, nothing :(

I have tried starting my PC with my windows disc in but it won't boot, I just keep on getting a message saying something like 'components missing', I can't remember the exact message and now my computer is in a bag waiting to go to the fixer in the morning.

I had done this action before on an older computer and didn't have any problems.

This time I followed all of the instructions properly but when I go to stage '17. Push the keys: Ctrl+Alt+Del' my screen just went black, any ideas?

I did this tweak to 2 64 bit machines and one 32 bit machine so it does work, but I have not tried it lately so there might be a incompatiblity with a update perhaps, but its more likely you messed something up very simple. It took me 6 tries to get this right. If you edit one of the files incorrectly by leaving even a space it will not work.

This time I followed all of the instructions properly but when I go to stage '17. Push the keys: Ctrl+Alt+Del' my screen just went black, any ideas?

You can just restart your computer instead of logging off. Now why the log off screen is going black im not sure.

Good idea, but 20 steps may cause some noob to brick their system. Is it possible to make a .bat file or reg hack to do this? Just curious. :)

I would like someone to edit and save the file for me Pre-Removed in 32 Bit Format because I will probably muck up again :(


Please can you confirm if this is correct

one thing... this may sound a bit strange but I have been doing a lot of customizations on authui.dll after i did this and want the ease of access center back! Lots of customizations means lots of backups. Should I use the original and lose my customizations or should I leave it and do something else?

Hello Thomas,

If the authui - backup.dll backup of the authui.dll in step 15 of OPTION ONE was done after the customizations, then you could just need to rename it like in that step to restore it. :)
