Windows 10 and mobile wi-fi router

[ecb]

I have a desktop pc running Windows 10 that I sometimes use to access the Internet using a mobile wi-fi router (which work has lent me during the lockdown in case I had to self isolate), I don't have landline Internet access at the flat.

Earlier this week I went online to look at my work email, I hadn't been online on the pc for a few weeks. I didn't do any web surfing but when I looked in the Network and Sharing Centre, I found that in that session that I had used over four gigabits of data. Some of this would be the updating of my anti-virus, but as as I can see the vast bulk of this was Windows updates, I have no problem with security updates but the size of the updates seems excessive, does anyone know a way of reducing this, please?

I will have to return the mobile wi-fi router to my employer soon and I am interested in buying a pay-as-you-go mobile wi-fi router for my own limited use and I don't want to waste my data allowance.

All you need to do is turn off automatic updates, Regards, Tom.
