-LED displays have better contrast ratio as compare to the LCD display.

How to change Text on XP start button.

Step 1 - Modify Explorer.exe File

The file explorer.exe located at C:\Windows. It needs to be edited.

It is a binary file and requires special editor for modifying.

I have used Resource Hacker.

Resource Hacker is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executable and resource files (*.res).

It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

You can get this from http://delphi.icm.edu.pl/ftp/tools/ResHack.zip

First of all you have to take backup of Explorer.exe, which is located at C:\Windows and place it in a folder somewhere on your hard drive where it will be safe.

Run Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

Navigate to category "String Table". Expand it by clicking on the plus sign then goes to the string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the string table. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

Double click on the word “start”, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Type your new entry.

After the new text string has been entered the Compile Script button that was grayed out. Now it is active.

Click on Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows.


Step 2 – Modify the Registry

Make a backup of your registry before making any changes.

Go to the Start Run and type regedit. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.
