Tethering is a super useful option included in almost all operating systems, from phones to PCs. It allows you to share an internet connection from a mobile device to a desktop computer or laptop. The only down side to tethering is that some operating systems, such as Windows, like to automatically start searching for and downloading updates the moment a connection is found. This aggressive tactic can put your mobile data reserves at risk, thankfully, you can limit most of this unwanted activity whenever you are tethered.

How to Backup your Computer Using Google's New Backup and Sync Tool.

The most common way to use your smartphone’s internet connection on your PC is by using the WiFi hotspot option on your device. Using this option allows you easily connect your computer to the Internet as if it were an ordinary WiFi network. In the past, the best way to limit what Windows would automatically download was to configure the connection as a metered connection. Unfortunately, from the creator's update onwards, Windows will forcefully download what it deems as critical updates, regardless of the type of connection you are using.

Even though the rules have changed somewhat for metered connections in Windows, you should still make sure you are using a metered connection if you are tethering. If you generally have your computer connected to a normal Internet connection, without any limits, it should be up to date anyway. It's also important to mention that when using a metered connection Windows will also stop all Windows Store app updates and live tiles cycles.
