I installed the "System Hardware Update - 11/12/2013" on my Surface Pro on 11/12/13. The Update history shows it was successful. I have Windows Update set to check for updates but not install them automatically. I just noticed today that it was reinstalling the same update as if it were new: A check for updates on 11/21 showed the same update as if it hadn't been installed. It installed again successfully. A check for updates on 11/23 showed the same update as if it hadn't been installed. It installed again successfully. A check for updates immediately after the install doesn't show the update needing to install. It shows up a few days later. What is going on? Why does it keep detecting that the same hardware update needs to be installed? I have BitLocker installed. Could that be the issue? This is the first time I've ever seen Windows Update reinstall the same update.
