Filtering a tethered network

When tethering my laptop to my phone (via WiFi), I would like to only allow certain "services" (email, HTTP but not Windows updates) through due to data limits on my phone and am wondering if this is even possible.

Looking for solutions to configuring either the phone (Android) and/or the laptop (Windows 10) when on that specific network.

Like an outgoing firewall on the laptop? when connected to that particular wifi network (my phone)

Cheers,
Rob

One option is to set the wifi connection as metered. This means apps will use less data and updates won't download.
To do this go to the Network and Internet Settings. Ensure Wifi tab is selected on the left.
On the right select Advanced options and then turn on Metered connection.
You'll have to set this for each individual wifi network you connect to. Ethernet connections don't have this option.

If you have Windows 10 Professional, Enterprise or Education edition you have another option in group policy.
You could use this to set updates as notify to download and notify to install. This way you have to approve when to download. You would still get prompted repeatedly until you do.

To use group policy click the start button and type gpedit.msc and press enter
Go to Computer Configuration\Administrative Templates\Windows Components\Windows Update
Double click Configure Automatic Updates and select Enabled.
In the Options box, pull down the Configure automatic updating menu and select the second option.
Save the settings and reboot.

You could also use group policy and point the updates to a WSUS server that doesn't exist.
The issue with that then would be you'd have to undo the change when you want updates again. I wouldn't recommend this but stated it in case it suits.

Thanks, that really helps.  Do you have any more information about how the metered stuff works?  Any way to configure it?

This is the FAQ from Microsoft https://support.microsoft.com/en-us/help/17452/windows-metered-internet-connections-faq

In the Windows settings it is basically either on or off.

You can go to individual apps and turn off their syncing when on a metered connection. The FAQ above has information on OneDrive, driver downloads and Bing search. Basically if the app comes from Microsoft and is certified for Windows 10 it should have a setting to not sync/download when on a metered connection.
