In the below example I am automatically deploying Microsoft Office to all computers in a particular GPO.
Open Group Policy Manager and navigate to the OU which contains the computer objects you would like to deploy office to. Right click on the OU and select “create a GPO”.
Once the GPO is created. Right click on it and choose edit.
Navigate to the software installation folder (as shown below). Right click on “software installation” and select “new” then “package”.
Then browse to the .msi you want to install using the network share. – i.e. \\server\share. It is important you browse to this by share and not by the c: or d: drives.
Unless you need to specify additional options choose “assigned”.
The deployment is complete.
