I have seen this issue reported on the VMware Community Forum a few times, when you run vCenter 7.0 you will receive a message in the vSphere Client stating the following “New vCenter server updates are available”. When you then click “View Updates” however you will notice that there are no updates available for vCenter Server and you are indeed running the latest and greatest version. We (Cormac and I) actually encountered the issue in our lab as well, which is demonstrated in the screenshot below.
Pretty confusing indeed. Please note that this is a known issue, there’s no need to report this to VMware. Soon a patch will be released for vCenter Server which will fix this problem.
