Customizing BgInfo to include the installed runtimes

Almost without exception, Windows developers use the tools from Sysinternals such as Process Explorer.  Another one that I've recent adopted is BgInfo, which displays useful system info on your desktop to save time and help distinguish multiple machines (Hyper-V users, you know what I mean).  I often find myself checking to see which .NET Runtimes are installed on a machine.  Standalone, BgInfo doesn't include any information about runtimes, but it does allow for customization, and that's what inspired this post.  I wrote a small script that will list the runtimes it finds installed on your system - when called by BgInfo, the runtime versions will be displayed on the desktop.  To use, just create a file called "runtimes.vbs" with the following contents.  Then run BgInfo, press the "Custom" button, "New", type ".NET Runtimes" for the Identifier, select "VB Script file" and enter the path of the runtimes.vbs file.  Running BgInfo from your startup folder keeps the information up-to-date.
