EZ Reregister Lite is now available as freeware. The software is "as is", and won't be developed any further. It has all of the functions of the Full version or the Online version, except it won't create any emails. It will allow you to store the names, registration codes, and vendor emails for all of your third party applications for future reference.

It's available on the downloads page at EZ Reregister.

I am getting a DNS error when trying to access that page.

Update: I was able to get to it now.
