How to slipstream updates into Windows Server 2012 R2 DVD/ISO

Dear All,

I have a Windows Server 2012 R2 Standard/Datacenter DVD (or rather, its ISO file), and I would like to add all the updates available so far into the installation, so when I use the DVD/ISO I do not have to spend several hours waiting for all the updates to install on the new server. Is there a way to:

1) get a list of the Windows updates necessary;

2) download the updates from the list in a way that does not involve doing them one by one; and

3) add the updates into the DVD/ISO (I believe this is called slipstreaming).

I do not have a System Manager server to play with in case someone mentions one.

Thank you in advance for your help.

Yours,

FD
