Windows 10 haven't updated to version 1511 --- How to find product key

I haven't run the ISO disk as of yet, I want the current product key in hand, on a post it note, prior to doing that, not interested in MS bullS**T about it not being needed. 2 hours online with tech support and they can't cope with the question of how
can the current product key be accessed in windows 10.

I've never owned a Apple product, but I can never see buying or having another MS product in my household after this.

NOT THE ONLY ONE

 

How to Install Windows 10 on Devices with Limited Space

Even though I have an external device with more than 40 Gb capacity and the assistant recognizes it, it still keeps asking me to free 5 more Gb from the (unit C.

I have 3'62 Gb free memory in (Unit C. It asks me to free 5'63 Gb more. That'll make a total of 9'25 GB. The assistant needs 9'80 GB free memory to update windows 10 without any external device. Does this mean that my external device will only be used
for 0'55 GB? Please I don't understant anything. I just want my laptop to work. I'd stay with my actual version but it keeps showing me ads, interrupting my work and deleting random stuff because of uninterruptible random updates. It has already freed 3 GB
and I dont even know where from.

Thank you.
