SYMPTOMS

When you try to open a Microsoft Office Word 2007 document, a Microsoft Office Excel 2007 document, or a Microsoft Office PowerPoint 2007 document in Windows Internet Explorer 7, the document may not open in the same window as Internet Explorer. Instead, a new Word 2007, Excel 2007, or PowerPoint 2007 window opens to display the document.

CAUSE

This behavior is by design. The 2007 Microsoft Office system intentionally does not set a BrowserFlags registry key for its file types. This behavior keeps 2007 Office files from opening inside same window as Internet Explorer.

Certain editing features are available only when the document is open outside the Web browser. Additionally, the Office Ribbon may not work as expected in Internet Explorer. Also, security enhancements to Windows Internet Explorer 7 running on Windows Vista make opening the document outside the low-integrity context of Internet Explorer (when running in protected mode) better for overall security and usability.

WORKAROUND

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Note For applications that require Office files to open inside the Web browser window, use the following workaround. However, this Internet Explorer feature may not exist in future operating systems that are later than Windows Vista.

If you have an existing application that requires the old behavior, you can modify the registry to allow the 2007 Office system files to open in Internet Explorer. We encourage you to do this only if the situation requires it. If you make these changes, all users of the computer will be affected.

To work around this behavior, follow these steps:

Start Notepad.

Copy and then paste the following text to Notepad:
