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.

 

Simplest method is to decline the EULA when prompted this will roll back to your previous install

If for some reason you have already accepted this have a look here ...

Downloading or actually installing? What message do you see on the screen?

 

Thanks, but what is realistic time needed for update ? Hours, days... .?

 

Like I said? Is it downloading or actually upgrading? What screen/message is showing on screen? It may be waiting for you to click an button? The actual upgrade should be only an hour at most, for most people. The actual download of the install files can take days but that should happen in the background.

 

I find (and sorry if it is not a helpful comment) that for me upgrading my 2013 i5 laptop takes about 20 or 30 minutes.

You may decide you don't like 10 and you can then revert back. This process (for me) takes longer for some reason than the upgrade. Perhaps an hour to revert to an earlier version.

Neither process takes hours or days.

I'd take the upgrade personally as (if you do it now) you'll get your Windows 10 permanently activated. After next month you'll have to pay for it.

 

There is no message on the screen - just circling mouth mark...

 

Hard reset. The upgrade will give up and you'll end up back on 7 again.

 

If it's been two days on that screen its likely never going to go any further. Try ctrl alt del and if that doesn't work your likely going to have to do as advised above. Press and hold the power button to force a shutdown and hope it recovers OK.

 

Ok, after hard restart prompt to begin installation has appeared, how may I decline ? Thanks to All.

 

It all depends on what the option are on the screen you see? If you see a "Do it latter" click that.
