Microsoft silently preparing your PC for Win 10

With 20Mb/s download it should take a few hours. I have that too and it took 6 hours to download 10049 update. But as was said earlier, it will also depend on the time of day.

I use Ethernet. It took 6 hours for 10049.

We have a 20 Mbps connection. So, I don't know how good it will do.

8 bits (b) = 1 Byte (B) >> 20Mb/s = 2.5MB/s

If an ISO is 2.5GB (2500MB)** >> 2500/2.5 = 1000 seconds

It will take a minimum of 1000 seconds to download.

As a rule, you are not likely to sustain maximum download speed during any given download, due to varying network conditions.
Also, not all of your download speed is used for the file you are downloading.
There are additional bits included in your download data stream (e.g. error checking, delivery IP address, etc.).

So it will take longer than 1000 seconds to finish.

What does this update(s) achieve exactly? Does anyone know for sure?

I don't think anybody knows for certain. But there are plenty of conspiracy theories. It looks like it will trigger something when the 10RTM is out. Maybe a message or a link for an upgrade. It is probably wise to keep an eye on it and get rid of it when it gets bothersome.

I'm using WiFi on my Windows 7 Laptops and Ethernet on my Windows 8.1 Desktop.

Is that something to do with the update?
