I am perfectly aware that you are tracking RAM usage.
However, the point I was making is ...there's both RAM and VRAM inside your PC .... both behave identically with respect to the context of the discussion.
A program or game will look at the amount of RAM in your box and allocate an amount for its usage. It is important to make a distinction between allocated and used.

Users who stopped Win 7 from constantly nagging about Win10 found themselves waiting hours and hours for WU to perform. This was part of MS's needling trying to push Win 7 / 8 users to Win 10 when they weren't meeting contractual market penetration with partners. A later KB fixed that problem.
On Win 10, the 1st two things one should do upon installing Win 10 are:
1. Turn off Windows ability to install Hardware drivers

2. Turn off Automatic Updates.... and you enable / disable when you want to do updates

We generally do updates around 48 hours after they come out.
