Windows 10: Took comp. for diagnosis...back, I can't open my files!!!

[Dell desktop; Chrome & Firefox browsers; Thunderbird & Gmail emails; Win10; now typing on a Lenovo laptop.]

The man says all he did to diagnose it, was to remove my HD put in his and put back my own HD. But at home I couldn't open any of the icons on the start page, some icons were all white and none opened, not even the start button. He offered to try to get all my files at $25 per hour for which I had to buy a HD extension, etc. - not even giving guarantee of saving my files!

However, on a corner of the screen it said my Windows is not activated, to go to settings to activate windows. There, they asked for the Windows 10 License Number. But I can't get into that page where it shows the number. I got Windows 7 with the purchase of my computer, and later Windows 10 installed itself but...is there any way I can get my License Number so I can retrieve all my files? Anyone please?

Thanks ever so much for any ideas!
