How much internet data will Windows 10 automatic (compulsory) updates consume?

[Windows Central Question]

We in South Africa do not have the luxury of affordable/cheap constant internet connections like in the UK/US or other first-world countries.
We buy (prepaid or contract) monthly data from a supplier like Telkom (similar to At&T) or Vodafone etc. This data comes at a hefty price per Gb, especially if you buy smaller bundles. Larger bundles works out very cheap per Gb, but expires after 30 days, meaning unused data is not carried over to the next month.
You simply forfeit it.

Thus: Before we can just hop along the free W10 ride, we need to know:

1.) How much of our PC's will be usable for regular home tasks if we do not have a constant data connection every day? In other words: Will W10 not operate properly without a constant data connection?

2.) It is all good to receive W10 for free, but how can we rest assured that W10 will not gobble up our data like a hungry beast due to the fact that it INSISTS on constant communication, leaving us stranded with but a few kb at the 10th day of each month (just enough to send a low-res angry emoticon to Microsoft...)?

1) Yes you can use Wiindows 10 properly

2) you have the option to set you connected as a metered connection which will allow apps to reduce data usage. ... There is also a data usage option that will tell you what is using all your data and finally : Set your data limit - Microsoft Windows
