use of Office Suite 2007

If both Microsoft 365 and Office 2007 are installed, remove Microsoft 365 and then open the Office 2007 applications from their own Start-menu entries; a valid Office 2007 licence does not require purchasing Microsoft 365.

Remove the separate Microsoft 365 installation

1. Close all Office applications.
2. Press Windows, type Control Panel, and open it.
3. Select Programs > Programs and Features.
4. Review the installed-product list:
   • Keep the entry explicitly named Microsoft Office 2007, such as Microsoft Office Home and Student 2007 or Microsoft Office Professional 2007.
   • If there is a separate entry named Microsoft 365, select it and choose Uninstall.
5. Restart the computer.
6. Open Start and search for Word 2007 or Excel 2007. Do not use an old taskbar or desktop shortcut until confirming that it opens the 2007 application.

Uninstalling Microsoft 365 removes its applications but does not remove Word documents, Excel workbooks, or other personal files.^1^

If Microsoft 365 is not listed in Control Panel, check Settings > Apps > Installed apps, locate Microsoft 365 (Office), and select Uninstall.

If only Office 2007 is installed

The available information does not establish what exact prompt is appearing. Check these details before removing anything:

• Open Word and select Office button > Word Options > Resources > About.
• Confirm that the product shown is actually Microsoft Office Word 2007.
• Record the exact wording of the purchase prompt and whether it appears inside Word or in a browser.
• In Control Panel > Programs and Features, note every entry containing “Office” or “Microsoft 365.”

Do not apply registry instructions intended for Office 2016/Microsoft 365 activation prompts. Those instructions target Office version 16.0 and are not documented for Office 2007.

Important support limitation

Office 2007 reached end of support on October 10, 2017. Microsoft no longer provides security fixes, bug fixes, or assisted technical support for it.^2^ Its licence may remain a perpetual licence, but that does not make the software supported or secure on a current computer.

For documents used regularly—especially files received by email or downloaded from the Internet—the safer long-term option is upgrading to a supported one-time-purchase Office release or Microsoft 365. Older Office versions can also experience unsupported or unreliable connectivity with Microsoft 365 services.^3^
