Where is the registry location for installed third-party software on Windows 7?

I just wanted to search for registry keys belonging to a third-party software I just installed on Windows 7, but I don't know where to look.

Are there defined spots in the registry where third-party software puts its keys?

Typically, 3rd party software places their registry keys are put in HKEY_LOCAL_MACHINE\SOFTWARE.

Also check in HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE (32-bit software on 64-bit machines)

And the programs could be listed in \Microsoft\Windows\CurrentVersion\Uninstall (Inside the both keys by @Keltari and @jtreser) which reveals many useful software installation and uninstall information.
