The startup welcome screen of Windows XP is in the logonui.exe file under the system directory "C:\Windows\System32" (logon means login, and ui should be the user interface graphical interface).

The tool we want to use here is "Resource Hacker", please go to the Internet to download the installation-free version (452K). To add a right-click menu, please open the "Menu.reg" file with Notepad and change "@="C:\\Program Files\\ResHacker\\ResHacker.exe %1"" to the actual location you extracted it to. (such as "@="D:\\GreenProgs\\ResHacker\\ResHacker.exe %1""), remember to use "\\" as the directory separator instead of "\" or "/".

There is another software ExeScope, but it is slightly overshadowed here because it cannot change "UIFILE".

Now use Resource Hacker to open logonui.exe (remember to back up).

1. Find the "Bitmap - 100 - 2052" branch. The circular gradient picture on the right appears in the upper left corner of the welcome screen. Its size is 219×207. Next select "Action - Replace Bitmap" or press F2, and select the BMP image you want to place in the upper left corner (prepared in advance), and press "Replace".

2. Select the "UIFILE - 1000 - 2052" branch, press CTRL+A in the right window to select all and then press CTRL+C to copy, press CTRL+V in Notepad to paste, and then press CTRL+ F Search for "219" and find the sentence "content=rcbmp(100,0,0,219rp,207rp,1,0)". Replace 219 and 207 with the width and height of your custom BMP image. Mine is "content=rcbmp(100,0,0,366rp,404rp,1,0)".

3. Press CTRL+H in Notepad and look for "90,126,220". This is the background color of the welcome interface. I changed it to white "255,255,255".

4. Press CTRL+H and look for "0,48,156", which is the dark blue bar at the top and bottom. You can replace it with your favorite color.

5. Press CTRL+H and look for "239,247,255", which is the color of the user name.

6. For other related colors, you can search for the keyword "rgb" to get them.

7. After all changes are completed, select and copy all the text in the notepad, return to the "UIFILE - 1000 - 2052" branch of Resource Hacker, press CTRL+A in the right window to select all, and press CTRL+ V Paste the changed text in and click "Compile Script" in the upper left corner.

8. Close Resource Hacker and it will prompt "The resource has been changed, do you want to save it?", click "Yes", select a save location (as long as it is not under system32), and save it as "logonui.exe".

9. The last step is to find a way to replace the system file with logonui.exe. However, due to the file protection mechanism of Windows, we must enter safe mode or use third-party software "Replacer", "CopyLock", etc. To complete the replacement
