256986 Description of the Microsoft Windows registry


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.


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.


Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

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:

  1. Start Notepad.
  2. Copy and then paste the following text to Notepad:

    Windows Registry Editor Version 5.00

    Note The following additional options are available for PowerPoint 2007:

    • To open PowerPoint files in the edit mode in the Office suite, use "BrowserFlags"=dword:0000000a.
    • To open PowerPoint files in the presentation mode in Internet Explorer, use "BrowserFlags"=dword:00000000.
    • To open PowerPoint files in the edit mode in Internet Explorer, use "BrowserFlags"=dword:00000001.
    • To open PowerPoint files in the presentation mode in Full Screen mode, use BrowserFlags"=dword:00000008.
  3. Save the file as FileName.reg.
  4. Double-click FileName.reg to run this registry script.
  5. Start Internet Explorer 7.


This behavior is by design.
