Marking a limited network metered tells Windows and some apps to reduce background data use. Microsoft notes that some updates will not install automatically on a metered connection, so the setting is a cost control rather than an update pause with no consequences. It matters when tethering through a phone or using a capped broadband plan. Make a specific update plan so a saved gigabyte does not become months of missing security fixes.
Before you start
Check your plan's data cap and current use with the provider, not only Windows' estimate. Note which network is expensive; a household Ethernet link may be unlimited while a phone hotspot is not. On a managed PC, IT can control the setting. Keep power and enough disk space for updates when you later switch to an unmetered network.Do it step by step
- Open Settings > Network & internet > Wi-Fi and select the currently connected network, or choose Ethernet for a wired connection. Turn Metered connection on only for the connection that incurs cost.
- Review Windows Update > Advanced options. If a critical update must install now, Microsoft's setting Download updates over metered connections can permit it, but confirm that the data cost is acceptable first.
- Check apps and cloud sync individually. Metered mode may change their behavior, but it does not promise that every third-party app stops all transfers. Pause a large optional sync through its own control if necessary.
- Use the phone or router provider's actual data-usage view to see whether consumption fell. Windows' setting is a request to software, not a carrier billing limit.
- When you reach a trusted unmetered connection, review pending Windows and application updates, install them, restart and verify completion. Keep this as a calendar habit if you tether frequently.
- Return to the capped connection and verify its Metered switch remains on. Record any app that ignores the hint and configure that app directly.
