Well,
after shut down of the AVIRA virus scanner, the download finally worked fine, after many failed trials before, on all of our five W7PRO machines.
I am using a low power desktop , 20W, AMD E350M1, µATX, with Samsung 128k SSD plus 1TB Seagate.
Purpose also is to log data from Lady Heather from the Thunderbird GPSDO on low cost.
I always had problems, to watch Daves 1080p50 videos with the Internet Explorer, had to use 720p50.
Anyway no chance at all with Chrome or firefox, as their video machines require too much graphics power..
The migration to W10 also copied the old IE11, and what a wonder!
Even the 1080p50 runs absolute smoothly, with usage of Flash player, or with the built in HTML5 features!
Great improvement!
Edge is not yet running stably, there's often a video error from YouTube, but once I could also watch these 1080p50 there, smoothly.
During the first sessions , the machine was very slow for boot up (40sec instead of 26 before), and the start of any program was very slow.
I completely removed the virus scanner, using the W10 firewall and virus protection only..
So latter problem improved greatly, and obviously got better and better when using the machine more often.
Only the boot time still was too slow.
But there are nice new features to check out the problem..
Call msconfig => Start , this will redirect you to the Task Manager.
There you can see, which autostart program are slowing down the boot process.
In my case, there were two National Instrument programs (for GPIB card), and that horrible Samsung phone manager KIES, which had "High" impact, so I deactivated them from autostart.
(Galaxy II phone is used for Keysights BenchView ;-)
After that, the machine now boots and works like a charm.. naked W10 boot time (w/o BIOS) is
17sec 14sec 12 sec only!
Engaging energy saver mode and back is also faster than before.
For sure, you have to disable these dangerous modes, like P2P SW updates
, and the whole "spy" programs and features, which are common on tablet and phones... For the rest of MS conditions , I'm not really afraid of..
Done that, this more modern W10 is highly recommended, especially as the upgrade is free and will last the next decade(s).
