I have upgraded two of my W7 computers this week to W10.
Take note that
you do not have to wait in line for all the W10 files to download to your computer and then be notified by MS when you are ready to go.
You can upgrade on the spot using Microsoft's media creation tool.
Plus, this tool lets you burn a W10 ISO DVD or USB stick if you want to do that
Download the 32 bit or the 64 bit media creation tool here
https://www.microsoft.com/en-us/software-download/windows10Install the media creation tool
Choose "upgrade this computer now"
Your W10 upgrade starts immediately
One of my W7 desktops took less than 15 minutes to upgrade to W10
Another one took over an hour
It depends on what software you have installed
It looks as though a bunch of windows updates were done during the W10 install
Windows Updates that I had previously hidden
That may have been the reason that the 2nd PC took way longer to update?
I have Office 2007 installed on that PC and had hidden a bunch of updates for office
Notes on which editions you getIf you have a previous home edition, you will get a W10 Home edition
Note that you may be missing some features you need if you upgrade to W10 Home
Better look at the list on this page to see if anything you need will be missing in W10 home
In my case, I need remote desktop
Remote desktop was standard in W7 home
Remote desktop is not included in W10 home
This page shows the features for all the W10 editions

In order for me to get W10 pro, I had to update one W7 computer from W7 Home premium to W7 Pro first
The cheapest way for me to get W10 pro was to buy a W7 pro SP1 upgrade for $59 from Software Plaza.
All you need is the W7 pro activation key that they send you.
For the $59, you get the activation key and you can download a W7 pro ISO file if you want that.
Doing it this way is way cheaper than upgrading W10 home to W10 pro.
Here's the link for W7 Pro for $59
Microsoft Windows 7 Professional 32/64 bit Full Version SP1
https://softwareplaza.com/microsoft-windows-7-professional-32-64-bit-full-version-sp1-1241.htmlTo upgrade W7 from home to pro: In the W7 control panel, use the "Windows Anytime upgrade" option.
Insert your W7 pro activation key and W7 Home updates to pro in less than 10 minutes.
It took 4 minutes on my desktop.
Then activate W7 pro in the control panel/System screen
Now you are all set to get Windows 10 pro when you do the upgrade
