|ENVy 1.1 (last freeware version) allows the environment variables of two machines to be compared and highlighted for differences. ENVy was written for the times when you've asked 'Why does it work on your computer?
What's different about your environment?' In addition to comparison, ENVy allows the differences in variables and values to be easily merged into your local environment by using a single right-click action.
ENVy also provides full capability for the creation, editing, deletion, and renaming of environment variables and values using a user-friendly, vertical display of values.
Requires .NET 3.5
