I did not buy a new windows, but found out something interesting.
You can activate windows 10 with a windows 7 key, 100% legal.
Only two restrictions, its needs to be the same version (you can’t go from home to pro or something like that ) and it needs to have the same language setting.
32 or 64 bit does not matter though.
Today I installed windows 10, and typed in the windows 7 key.
After installation I checked, and all went well. I now have a windows 10 pro 64 bit installed. ( my windows 7 32 bit is also a pro version )
Now I am waiting for a sata cable, so I can hook up the second hard disk and install leap 15.1 on it.
I do have two sata cable, but it has two straight connectors, and that won’t fit. There is not enough room for a straight connector to the hard disk.
I need a cable with a connector under 90 degrees at one end.
