Hello To get back old start menu go to the link http://www.csmenu.com/ And download Csmenu
Double click the CSMenu exe file to get things started. The install process for CSMenu is quick and straightforward. After finishing the installation, you will see a message window that will say that CSMenu is going to index your Start Menu. Once it has finished indexing, you will need to log off and then log back into your User Account. After logging back in, go into the Start Menu to locate the CSMenu folder. Right click on the “Show CSMenu” shortcut and select “Pin to Taskbar”. Once you do that, there is your new Classic Menu Start Button right next to the original one (you made need to move it to the left in your taskbar). I have copied these instructions .I have not tested it .Hope it helps
