I understand the frustration you're experiencing with the cut and paste issue in Microsoft Word after installing Windows 11 update KB5031455. While Office 2003 is an older version not officially supported on Windows 11, it's still unfortunate that you're experiencing this problem. Although I cannot provide a direct solution to fix the issue, I can suggest a few troubleshooting steps you can try:
1. Run the Microsoft Office Repair Tool: Office 2003 provides a built-in repair tool. Go to "Control Panel" > "Programs" > "Programs and Features" (or "Add or Remove Programs" depending on your Windows version) and locate Microsoft Office 2003. Right-click on it and select "Change" or "Repair" to launch the repair tool. Follow the instructions and restart your computer.
2. Update Compatibility Mode: Right-click on the Microsoft Word shortcut or executable file and select "Properties". Under the "Compatibility" tab, check the box that says "Run this program in compatibility mode for" and select a previous version of Windows, like Windows XP. Apply the changes and launch Word to see if the issue persists.
3. Reinstall Microsoft Office 2003: If the repair tool doesn't resolve the problem, you can try reinstalling Office 2003. Before proceeding, make sure you have the installation media or setup file for Office 2003. Uninstall Office 2003 through the "Control Panel" and then reinstall it using the installation media.
4. Consider Upgrading to a Supported Version: Since Office 2003 is no longer officially supported, it may be worth considering upgrading to a more recent version of Microsoft Office. Newer versions have improved compatibility with Windows 11 and receive regular updates and bug fixes.
It's important to note that the above suggestions are just general troubleshooting steps, and there's no guarantee that they will fix the problem. Given the age of Office 2003 and its lack of official support, compatibility issues with newer operating systems may arise.
If none of the above solutions work, you may want to explore alternative word processing software options that are compatible with Windows 11. There are several free and paid alternatives available that can provide similar functionality to Microsoft Word.
Additionally, you can report the issue to Microsoft through the official Windows Feedback Hub. This will help Microsoft investigate and potentially address the compatibility issue in future updates.
I hope these suggestions help, and I apologize for any inconvenience caused.
