Windows is using your internet to update other people’s PCs — disable this hidden setting to speed up your connection

Don't let Microsoft zap your bandwidth by disabling this setting

My recommendations:
- Enable ONLY on the LAN
- Disable sharing via the Internet
- Restrict via GPO, Local Network Only mode
- Control via firewall (DO ports)
- Limit bandwidth (QoS / policy)
