I just upgraded from Windows 8 to Windows 10 (both 64-bit) and my previous Eclipse Juno with ADT-plugin for Android development is no longer starting.
All I can see
Retain single version of java and uninstall all other versions
and update the eclipse.ini text file as below but change the java path and versions appropriately.
-startup
