We are managing our Windows updates with WSUS 3.2 and just recently discovered a strange issue. One user saw the notification popup earlier this week and chose to install manually. All the updates appeared to have installed but shortly thereafter, three cam back and showed as still being needed. He tried several more times and each time the installation would run with no apparent errors and a few seconds later the notification would reappear in the SysTray with the same updates. He also noticed that the remaining updates were "grayed out" in the custom installation screen, which isn't usual.
I checked the WSUS server and those updates were approved, downloaded and ready for install and showed as needed on his system. They also had a deadline set for next week which I thought might be causing the strange behavior. I cleared the deadline on the three updates in question and ran the updates from the workstation again. Two went away but one still came back as needed.
I then looked at the WindowsUpdate.log on the workstation and found the following entries from the last attempt. I've bolded the two lines that caught my attention. The log shows that the files are already installed and valid and then shortly after completion of the install process, another event appears that shows the same update as downloaded and ready for installation.
Does anyone have any idea why this is happening?
