im in the process of creating the company 'model' client machine, its based on windows 7. and i was wondering if i need to install the updades to all the versions of .net framework installed, or i could just upgrade to .net 4.5 and install only the updates for this version?. in other words.. do i really really need to install updates for legacy frameworks?..or the .net 4.5 include the security updates for those old framework?.
Thanks..and sorry if torturate the english.. ;)
Yes
Typically security updates represent important or critical updates from Microsoft that fix holes in current code (in this case .NET) that expose the client machine to potential attack.
Installing those updates is always recommended after testing them against your business software. You always want to try to minimize the attack surface area as much as possible and installing .NET updates, regardless of version is usually a very smart thing to do.
In addition, some 4.5 updates may not install properly if the underlying framework is not at the current version.
