Wondered if there was anything else we should be doing. We had two massive spikes in data usage recently. Usually we use less than 20Gb per month (fibre's hopefully coming as a Christmas present - guys on the street laying it now). The 20Gb is general usage, with biggest usage being Skype (when we use video for long sessions it can push our daily usage over 1Gb) and to a lesser degree TeamViewer (with clients). Also DropBox for the odd file but usually less than 100Mb each.
On 23rd we used nearly 5Gb, and on 25th 4Gb. Having been bitten before with Windows 10 chewing up bandwidth, we have Glasswire on our laptops, so can see it was my wife's machine that used this - and it was from MS. I assume the duplication of bandwidth was due to the first attempt failing - it took some time both times for the updates to install. Why it had to download twice is beyond me.
Given the amazing size of the download, I've enabled the option to update from other machines on our network - but that wasn't on at the time so may not work when it tries to update my system.
I hate my system doing things I have no idea about - not that I have much understanding of technical stuff anyway. So if anyone has any suggestions that might further reduce our bandwidth use - or at least understand it, I'd appreciate it.
Thanks
