Your thread deserve the merit point I gave it.
Many of my friends have tried upgrading it directly and it failed because their Internet bandwidth is very slow. A lot of them got hold of a pirated version and they think those are save to use, because they pirated previous versions of Windows and they had no problems.
Now, I can download the official ISO from Microsoft for them and give them a cheap option to make it legit. Thank you for this information.
I already told them that they will have issues with Electrum and Windows 7 + Chrome, but they are stubborn and want to risk it. In a way I want to leave them to learn from their mistakes, but on the other hand I do not want them to lose money.
Some of them bought second hand notebooks with a separate partition with the OS for recovery, but they did not receive any legit activation code for the operating system. I helped them to get the activation code from the OS that was installed.
