Nice idea but not quite feasible I think. Getting the information is easy with WMI and any programming language, but processing the results is quite another story. Most serial numbers use not only digits, but letters and punctuation as well. Apart from that, a lot of devices do not even return anything, leaving you with an empty value. On top of that you could never replace your defective CD Rom drive, memory module or any other hardware without having to modify your code and rebuild the application. The idea has been explored many times but I don’t think any commercial developer implemented it this way, mainly because good alternatives like a USB dongle are widely available.

I have been using my own solution to this for years:

1) Create a folder anywhere you like, with any name you like. I made mine in ‘My Documents’ called ‘QuickStart’.
2) Add the new folder to the path variable.
3) Create shortcuts to any commonly used applications or documents inside this folder and make sure the name of the shortcut is the command you want to use for it. For example, I made a shortcut to Visual Studio called ‘vs’. So when I execute the Start → Run dialog, I type ‘vs’ and the shortcut is executed because it’s in the path.

On top of that you can set all parameters like commandline arguments, working folders and Win95 compatibility emulation as well.

Very simple and no application needed  ;D
