Flashing blue screen before LogIn

[dis]

thx :)

[kroll]

Although you already managed to do this I thougt id share this, maybe it will come in handy sometime: I know that once I made my custom bootscreen with white background I would get a plain white screen before my desktop loads. The blue welcome message still pops up (I am trying to get rid of that rigt no, any help would be appreciated :) ) but before that its plain white.

I dont know if this helps

the "blue welcome" message is the default logonui.exe. you can change that with reshacker.

btw this blue flash is part of the original logonui.exe and the only way to get rid of it is hexediting. in some cases (fast cpu / hdd and lot of memory), this blue flash doesn't show up at all. but with slower pc it can be seen.

Already asked this in another topic and eventually I was going to start an extra one for this but since were talking about it, here is my problem with that:

I was trying to manually edit the logonui.exe, I was plannig on adding the bitmaps logonstudio created (but wasnt able to apply most likely cause Im on a 64bit system) and to change the background color settings in the UIFile (maybe its called something else, I dont remember exactly) section of the exe. Adding the bitmaps of course was easy and I was able to change the blue background into white, but even after changing every color value to either #FFFFFF or 255 255 255, the top- and bottombar remained blue.

Where are these colors defined or is there a way to edit my logonui with x64? Logonstudio or LogonXP wouldnt work.

Thanks!

check your ui file again. must be there somewhere. (+ there is a separator (divider) bitmap at the top / bottom)

as far as i know the only x64 pe editor is CFF Explorer suit. http://ntcore.com/exsuite.php

thanks dis, Ill take a look at that editor.

I was actually able to create and use a logonui.exe. This is how I did it:

I created the screen in logonstudio, since logonstudio isnt able to apply it I simply copied all the created file including the uifile.txt, opened my original logonui.exe, assigend all the bitmaps and replaced the entire uifile section and ended up with an edited logonui.exe which tuneuputilities can load and apply.

So I suddenly have this plain white logonscreen. This is ..kind of what I was looking for. There is only one problem that I havent been able to solve: whenever I edit my logonui.exe, the logonscreen wont display my username anymore. This is (like I mentioned above) kind of what I was going for (I am using autologon anyway and was going for a plain, minimalisitc look) Still, I would like to know why this problem exists. Even if I use my unchanged original logonui.exe and apply it with tuneuputilities this problem exists.

Another thing that was bugging me was that little blue box that appears for a short moment when the logonsceen appears. Its not the classic logong window but a plain blue 2x7cm window in the middle of the screen. It wasnt displayed the last times I started my system but it did at first and was very annoying (Ill post a screenshot soon)

[dis]

yeah. a screenshot (even with real camera) would be much help.

+ check if your username text color is white. because if it is white that is the problem. you can't see white text on white bg. or maybe tuneuputilities did something. i don;t know for sure.

dis,

You, Sir, are a genius! That has been bugging me for years.

Thanks for all your hard work!

Thanks dis!

It wasnt working at first but then I noticed windows had made another login exe called loginuiX.exe, so then edited that and hey presto!

I just found out that this works with winPE,

Originally when any PE booted, there was always a blue screen up for about 10 secs.

But this fixed it!

THNX!

this was one of the most annoying little thing in xp that annoys me a long time. but finally i did the hack. basically it is a quite simple hack. you only have to modify one single number to eliminate that blue flash forever.

requires a disassembler and a hexeditor.

load logonui.exe into a disassembler, then search for CreateSolidBrush . you will see this:

see that 74(15)? thats the problem. you have to change that number to 75(15) in hexeditor. when you select (green line in my disassembler) that line (7415) in a disassembler, you will see (in example in the status bar) what offset you need to search for in hexeditor. in my case it was at offset 771f but that number depends on what's your dll version or dll language.

done. no more blue flash when you lock the computer or when logging on/off.

for those who are not familiar with disassembling things. :)

here is the hexcode snippet where you have to change that 74: FF15F41000018BF085F67415568D45

search for it in hexeditor and change it. if you can't find this code snippet, try search for this: F085F67415568D. if you still can't find it, well, it seems you will have to use a disassembler first to determine the correct code.
