If you want to download the players and distribute them in your corporate network you must get a license from Adobe before doing so.
You can find the direct download links for each application here: Looking for Adobe Flash Player Download Links? If you are looking to disable the auto-update feature of Flash, go to the Adobe support site: IT Administration: Configuring Flash Player auto-update notification.
Installation of the the Windows Installer version of the plugins is very simple:
@ECHO OFF

START /WAIT MSIEXEC /I "install_flash_player_active_x.MSI" ALLUSERS=TRUE REBOOT=SUPPRESS /QB
ECHO Adobe Shockwave Player..
START /WAIT MSIEXEC /I "sw_lic_full_installer.MSI" ALLUSERS=TRUE REBOOT=SUPPRESS /QB
