An anonymous reader writes: The Guardian reports that some early adopters of Windows 10 are finding their computers stuck in a reboot loop after installing a particular update. KB3081424 is a cumulative update, packaging together a group of smaller ones for ease of installation. For some users, the update continually fails to finish installing before issuing a reboot command to the PC. "It downloads, reboot to install. Gets to 30% and reboots. Gets to 59% and reboots. Gets to 59% again and then states something went wrong so uninstalling the update. Wait a few minutes and reboot. Back to login screen," said Microsoft forum user BrettDM. "This happens without fail, every single time."
