Here is the registry hack to move the Menu back to the top in IE7:

1. Click Start, Run, and then enter regedit into the runbox
2. Press ENTER or click OK
3. Browse to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftInternet ExplorerToolbarWebBrowser

4. Click the Edit menu in regedit
5. Select New and then DWORD value
6. The name should be highlighted in the right column. Just type over this to name it:
ITBar7Position
7. Double click your new entry in the right column.
8. Change the value to 1.
9. Close regedit and open IE7 to see the change.

For those registry gurus... here's the process in one swoop:

[HKEY_CURRENT_USERSoftwareMicrosoftInternet ExplorerToolbarWebBrowser]
"ITBar7Position"=dword:00000001
