Make Internet Explorer show more sites on about:tabs homepage
To do so, open regedit and navigate to the following key: In the right pane in an empty spot right click and create a new DWORD and name it NumRows. Give it a value 3. Restart Internet Explorer.
You will now see 3 rows being displayed. You can give it any value between 2 and 5, with the default being 2. Lee adds: To use this registry edit, you will have to have history saved. If you have Delete Browsing History on Exit, checked, the registry entry for NewTabPage is deleted on exiting IE and you will have to recreate it each time you load IE.
