Hold (windows button +r simultaneously)
2. Type in regedit and hit ok.

Under that go to software, then to Microsoft, then to Windows, then to CurrentVersion, then to ImmersiveShelf, and finally to Grid.
4. Now go to edit (on the top left of the window), hover your mouse over *new* to get more options, and click on DWORD (32-bit) Value. Now rename it as Layout_MaximumRowCount. Next double click on it, a popup window will appear. Choose decimal and change the value to 3.
5 Go to file (on the top left of the window) and click on exit.
6 Restart your computer and you should be able to see the changes.
