I am having an issue with windows update through the NAC agent (clean access). I recently installed updates on my computer, but after the restart, it still prompted me with the "Download updates from microsoft" prompt. However, there are no updates to download, I am 100% up to date, and clicking update just locks up the agent and it does nothing. I have let it run for 2 hours and no change. My agent version is 4.7.2.10 and I am running windows 7 64 bit. I have tried uninstalling and reinstalling the updates in various ways, system restoring, etc, and nothing works. My boss is the network administrator and he found no reason on his end this should be happening, and other computers on the network do not have this problem, it is my machine only. Any advice would be a great help.
