Office 2003 and 2007 Office documents open read-only in Internet Explorer via SharePoint

After searching the web I found workaround that should workhttp://support.microsoft.com/?kbid=870853. According this article:

1. Quit all running Office 2003/07 programs.
2. Open register (regedit.exe)
3. Locate and then right-click the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Internet
4. Point to New, and then click DWORD Value.
5. Type OpenDocumentsReadWriteWhileBrowsing, and then press ENTER.
6. Right-click OpenDocumentsReadWriteWhileBrowsing, and then click Modify.
7. In the Value data box, type 1, and then click OK.
8. On the File menu, click Exit to quit Registry Editor.

After testing I was able to open file in the Edit mode.
