  • exit
  • ren c:windowsSoftwareDistribution SoftwareDistribution.old
  • sc config wuauserv start=disabled (temporarily disable auto-start service update center).
  • Close the command prompt and press «Continue» to restart the computer (boot up with the HDD, not a boot drive Windows 10).
  • If the system is successfully loaded in normal mode, enable the update service: press Win+R, type services.msc, locate «Windows update» and set the startup type to «manual» (this is the default value).
