After having decided that I wanted to install Windows 10 on my new SSD instead of doing a fresh reinstall of Windows 8.1 I finally got Windows 10 installed on the SSD in my main desktop computer and it is activated. But the process was not easy.
I first tried to install Win 10 on my new and empty Samsung SSD. For the install process to start I had to enter a valid key. I entered my Win 8.1 key retrieved by Keyfinder. The key was rejected and I checked and double checked that I had made no errors in entering the key. I then decided to do a fresh install of Windows 8.1 and accept that the W 8.1 key was not OK for the W 10 install or that the free upgrade had ended or only worked with W 7 (?).
I reinstalled W 8.1 from a DVD created from a downloaded ISO from Microsoft and installed a few programs more. Every thing was fine until I decided to check for updates from Control Panel. Even after having finished the checking with the result that no updates were available and the the update window was closed something seemed to cause a constant CPU load of 30%. Restarts did not change this. I thought that some system files had somehow become corrupted, but DISM and sfc /scannow from a command prompt found no errors.
As I had not installed very much more than OS and a few programs I decided to try if I could upgrade the W 8.1 install from the W 10 DVD I had made. I was asked if I would check for updates before the install. I accepted and the check started but ground to a halt at around 40%. After 10 minutes I cancelled the install and tried again. This time I refused the check for updates before the install. The install started and at some time I was again asked for checking for updates I accepted and this time the check progressed to around 60% before coming to a halt. After 10 minutes I tried running the install from the DVD a third time, this time refusing the search for updates during the install by checking "Later" or something like that. The install was successful and I was never asked for a key. Checking properties of "Computer" it was seen that Windows was activated. Windows 10 is running very well with this upgrade from a newly installed Windows 8.1. I think that what comes closest to a clean install is to install Win 8.1 and nothing more to an empty disk and then do the W 10 upgrade from Win 8.1.
Using "Keyfinder" on this new W 10 install I noticed that a new key different from my W 8.1 key had been used. The W 7 keys were not changed when upgrading to W 10.
I don't understand why I could use the W7 keys previously used on two other computers to do the W 10 install to reformatted HDDs and why the same procedure didn't work the W 8.1? Could it be because the W 8.1 computer has got UEFI and the W 7 computers have got the classic BIOS?
