Yesterday Microsoft pushed its seventh Windows 10 cumulative update, KB 3093266. If you run Windows 10 RTM, your system probably rebooted overnight. If you're unlucky, the update didn't install, and it will no doubt try to install itself again in the near future. Such is the nature of forced updates.
The Microsoft Answers forum has several reports. One from RCoover states:
Quote: After an apparently successful installation through Windows Update, the computer requests to be booted. During the boot, I get a message that the installation HAS NOT BEEN SUCCESSFUL and then continues to boot. Going into Windows Update Advanced, I find that the update did fail. I did this twice and it failed both times.
In a different thread, LeonardoDV says:
Quote: I'm at zero for three attempts on two computers to install this clunky monkey. There were no error codes, just "...couldn't finishing installing...." The last "cumulative update" was just as bad. I have a third computer to try (oh boy, another HUGE download on my slow DSL line). Wanna bet it doesn't work on that one either? Microsoft, on what PCs are you testing these updates? Do you only have three or four test boxes?
