There are actually lot's of ways but both methods discussed here so far works. Below are the steps I take to achieve the same.
Take note of the program location i.e. "C:\Windows\Installer\bb7400.msi" <- my own personal case.
Windows Key -> R (keyboard combination)
type cmd
press Ctrl -> Shift -> Enter
press Alt -> y
then type msiexec /uninstall C:\Windows\Installer\bb7400.msi
after uninstalling just type "exit" then press enter.
