The WAMP stack installer
rebooted my Windows 10 machine in the middle of the installation. I was able to cancel the reboot, and cancelled and reran the installer and it rebooted again! This time I didn't cancel the reboot. After the reboot, the installer seemed to install fine without any reboot.
Apparently, the same issue was reported a few months back and it was said that it was being investigated:
@Ibone, what is the result of the investigation on this? What is the cause of the reboot? I am deeply concerned about a virus :(.
