Windows 10: W10 doesnt activate after HD changing

I have been under w10 for 2 years on my laptop, I changed the HD to SSD and cannnot activate since then. I bought the computer with windows 10 preinstalled and I reinstalled it in a hurry 1 year ago. How can I activate ?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Important W10 activation key questions left unanswered by Microsoft

For the record, I just tried to copy and paste the .old file to an external HD. It was going OK, then it got hung up on "permissions".
I went to properties and clicked the box to unhide hidden files and tried to change master permissions.
W10 did not like what I was doing mid save.
In the end after applying changes, the .old folder was moved to the external and is now no longer listed on the C drive.

I don't know if it is even a viable folder anymore. The transaction was only supposed to copy the file, not remove it.

The rollback feature "button" is still present. I have not rebooted yet.
