Authorize te new computer. Open iTunes and select the store tab. Next scroll down and select authorize this computer

First you need to authorize your PC with your iTunes account with iTunes if you haven't already done so. With your iPhone connected to iTunes and without syncing, at the iTunes menu bar go to File and select Transfer Purchases From - the name of your iPhone.
Besides what mentioned above, i like to share you a article about How to transfer or sync iPhone to new computer, which included transferring iPhone contents to computer/iTunes.
​Hopefully this works for all of you like it just worked for me!
