Disable Windows Update

Published on 8/1/2026

Finally! Windows update was very annoying. Too much downloading & resource utilization. There was no options to disable it reliably.

Steps are as follows:

  • Run Windows 10 in QEMU.
  • In host, squid proxy has to be run in docker, no configuration is required.
  • In Virt-Manager, create a new virtual network
  • For guest NIC configuration, change network to new virtual network

For new virtual network XML, make following changes:

  • Copy paste the default network XML
  • Change network name, bridge name, mac address, IP address range
  • Remove NAT forwarding settings
  • Remove inside . Not sure if it is compulsory

Inside host, set proxy for firefox. Nothing else can access internet.
