Is there another way to get this, than off the bottom of the laptop. My sticker vanished a long time ago. I'm assuming I need it to upgrade from 7 to 10.

The Magic Jelly Bean will do it for you, and it's free.
 
 

Ahh cool. It's just my small travel and work laptop, hence the sticker going. Thanks for that

Looks like I have to pay fr the version that gives me the product key, but I think I can handle that. Seems from Noels Post that the laptop will run more efficiently and being just a little laptop, that may make more noticeable difference.
 
Plus my version of Windows has a fixed default Desktop back ground, so I can have something more interesting

No you don't need to pay, the free version will do it, I done it a week or 2 ago on Windows 7

Great tip, Jeff! Thanks. That could be a lifesaver someday.
 
My own insurance has been to maintain a master file that contains every serial number and product key I've ever installed, along with logins and passwords, bank account numbers and social security numbers for the whole family.
 
I've been copying that file forward from machine to machine for 35 years (its original incarnation was on an Apple ][ !). Granted, it would be a treasure-trove for an identity thief, but I keep it well-hidden and password-protected. 

Another thread has mentioned ProduKey.

Yes I do the same, except not for Windows, I usually have the book the CD, the box or whatever with the product key stored away, but for some reason I couldn't locate it for this laptop, that's when I had to call on the jelly bean.

I have the same as Bit, it's called the "blackbook" becuase it was originally a ,, that's  right, a little black book...
It's in drop box which is sort of scarry but it allows me to fetch passwords and serial numbers from any one of my many computers. 
It is encripted text that only I will understand as the passwords are not verbatium but clues like 
"Top Drawer".    see that means nothing unless you know what I keep in my top drawer. 
And bank numbers are cleverly noted as phone numbers.
 
A huge asset is to use dropbox screen capture as well. Like with Sonar, I have screen shots of my account pages and serial numbers. This is stored with a date so it's easy to look for the most up to date ones. 
If you have drop box instaled the first time you do ALT/ Prnt Scrn it will ask you if you want to store screen shots.

Technically, it is not encrypted text but hints and misdirection. It would probably be safer to actually encrypt the list of secure items on you computer, then upload that encrypted database to the cloud. In that case even a clever guesser, and the cloud provider would not have anything to grasp. I have been using Keepass, which can easily store passwords, account and registration numbers etc. as well as screen captures and other files as encrypted attachments. Of course you can still use your personal hint system within an encrypted container, steganography in attached photos or whatever. The database and the program can be loaded onto a USB stick and used on any Windows computer without installation, but that probably exposes you to security loss if the computer you use it on is compromised. So it, like every other security system you use is only as secure as the computer you use it on. And at some point, you are going to need to transfer the actual password to an application, which will make it available to a keylogger, screen reader, clipboard viewer etc. on the machine you are using. Public computers are as secure as a billboard printed with your passwords. The cloud, dropbox etc. is only as secure as your computer, any computer it passes through, and any computer or removable, backup or discarded storage it is saved to. And of course any account that lets you use a password hint to recover your password has a hole big enough to drive a truck through. So never use anything anyone can guess. City where you were born?
