HELP! screwed up authui.dll

[plutomok]

I was following steps to change / customize my windows 7 lock screen

one of the steps was to temporarily rename the authui.dll file found in C/WIndows/System32
 

unfortunately i got sidetracked by something else and didnt get around to pasting in the new authui.dll for the theme i wanted to install,

and i shut down my laptop before i completed the process

 

now my laptop boots into windows. but instead of the lock screen it now just shows me a blank black screen with the mouse cursor,

I typed in my password into the blank screen anyways just in case that would boot me into my desktop but it didnt....

 

I messed up, Im freaking out
Please help me LTTC

Thanks

SOLVED!
I plugged in my laptop's harddrive into my desktop 

and was able to go into the Windows/System32 folder and rename the file back to its original name

and now it works once again

 

*phew*

Try pressing Esc or F8 during the boot process. It should bring a safe boot menu, one of the options should be to do a system restore via the "Restore PC to last known good configuration" or something along those lines. Feel free to ask any further questions if you need any more help.

Ah good idea mate. Glad that you got it sorted. There is a lesson to be learnt out of all this isn't there, and I bet you know what it is too?
