Capturing updates to applications and operating systems
View Patent ↗An enterprise network management system is described for automatically updating program layers. A program is installed on a reference machine designated for the program and the reference machine is subsequently suspended. When the system detects a newer version of the program on a client device on the network, the reference machine is resumed, the program is allowed to update to the newer version, an updated program layer for the newer version is captured and stored, and the reference machine is suspended. Thereby, when a program layer for the updated application is required for IT operations, the layer will be available. The process can repeat when subsequent versions of the program are detected on client devices.

wherein the first program layer for the first version of the program is produced based on differences between the first snapshot and the second snapshot.
3. The method of claim 1 , wherein:
producing an updated program layer for the second version of the program based on the updating of the program on the reference machine to the second version of the program comprises:

detect a second version of the program on the client device based on the uploaded information;
update the program on the reference machine to the second version of the program; and
produce an updated program layer for the second version of the program based on the updating of the program on the reference machine to the second version of the program.
8. The computing device of claim 7 , wherein:
