After installing Tor (browser bundle) on my Win7-64 machine, it doesn't show up as an installed program in Programs and Features in the Control Panel? Is this normal or is this a glitch?

Because the 'Installer' just decompresses a zip archive that's been created as a .exe
.
To make it visible in the control panel you need a different type of installer that supports that feature.
The Tor Project's information page on the Tor Browser Bundle states:
The Tor Browser Bundle lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained.
It's meant to be completely portable. This means that when you download and unzip it (on Windows, Mac, or Linux) you're extracting a pre-compiled, ready-to-go executable. Each time you unzip it you're getting a fresh "install" so to speak, and all it would take to "uninstall" it would be to delete the folder containing it. The whole process of installing/uninstalling leaves as little trace on the operating system as possible.
