How to hack / change your logon screen in Windows XP Professional

This trick is very easy to do if you have already done the Start Button hack. If you don't already have Resource Hacker go download it now. Browse to C:\winnt\system32 or C:\windows\system32 and copy & paste logonui.exe into the same directory. It should name the copy: copy of logonui.exe Once you have done that, copy logonui.exe again and paste it to C:\ Now, open C:\logonui.exe with Resource hacker. Click on Action and then on Replace bitmap. If you are good with graphics you can make your own logon screen, you should be able to scroll thru the bitmaps in this file and figure out what's where. If your not great with graphics :/ like myself, you can download already made graphics and use them, or use them as a template. To set the size of Bitmap 100: Go into the \UIFILE\1000\1022\ tree and press CTRL+F Now, find Change the entire line to read: Where xxx is put the width e.g. 400rp (the rp @ the end is needed) and where yyy is, put the height e.g. 1000rp. Make sure the image doesn't go over the login names because it slows down to a snails pace (fading etc.)

Once you have everything the way you want it, just save the file to C:\ and close Resource hacker. Now, your going to need a Windows 98 bootdisk so you can get in dos mode. You can go here and download a bootdisk, if you don't already have one. Once at the DOS prompt, you must copy the new logonui.exe file over the existing one. Go to the directory where you extracted the new logonui file (C:\logonui.exe) and type: copy logonui.exe c:\windows\system32\ or C:\winnt\system32 on some systems. It will ask if you want to overwrite the file, just say yes. All done! Once you reboot you should see your new logon screen. If for some reason you screwup, go back in dos and copy the copy of logonui.exe file and replace it with the one in C:\winnt\system32 or C:\windows\system32.

I have a few templates here, that you can download and use:







ALWAYS BACKUP EVERYTHING YOU EDIT OR DELETE. I'M NOT RESPONSIBLE IF YOU MESS YOUR COMPUTER UP BY DOING THIS HACK. DO IT AT YOUR OWN RISK.

Until next time, Happy hacking! :)
