[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TabbedBrowsing\NewTabPage]
"NumRows"=dword:00000005
(Change the dword value to 00000003 for three rows and 00000004 for 4 rows)
4. Save the document as ie9_tabpage_pop_sites.reg.
5. Double-click the new file to merge it into the Registry.
6. Continue through the UAC prompt and confirm that you wish to perform the action.
