Hi Erin,
Just took a cursory peak at your Glasswire data ......:
First impression:
For the period 3/26 thru 3/31 (thus far) the lions share of your data was consumed by Win10's Edge browser .... and while we all have different browsing habits .... THAT IS A LOT OF DATA .... 9.1 GB to be exact.
I want you to compare that that to my Glasswire output for the same period:
While it is now secret around these parts that I'm not a fan of Win10 or (because I have Win10 on a test drive) or the Edge browser my suggestion is this:
Download and install Firefox. There is no need to make FF your default browser or any of those system changes ... Use Firefox for your daily routine, leaving Edge totally unused.
After a period of time, use Glasswire to look to see how much "browser data" you are using.
