Key-limited use applications are maintained at a central service where the central service can receive requests from a remote computing device for access to the key-limited use applications. The key-limited use applications include publicly available portions and a locked portions accessible with a key. The central service can provide a key to the remote computing device associated with a key-limited use application for complete access.

Unauthorized or unlicensed computing devices are prevented from using the applications.
