Unless you have a windows 7pro key RETAIL version or a windows 8 or 8.1 RETAIL Pro key. not a OEM key, their is no way to change your windows 10 Home to Pro on your new laptop, unless it came with Windows Pro version when you bought it. As far as I know.

If it comes back as a retail product key and not OEM:
1. I would highly recommend you make an image of your current Windows 10 Home. I prefer to use Macrium Reflect Free for that. Or be prepared to do a clean install of Windows 10 Home. The next step will permanently upgrade the Home to Pro - and if the activation step does not work, you will be stuck with a non-activated Windows 10 Pro.
2. Use the generic Windows 10 Pro product key (not "N" version, and not "Single language" version - N and SL require a different product key) to trigger the upgrade to Pro. On the activation screen from settings, use the change product key option.
This is the generic product key that everyone gets when then upgrade Windows 7/8/8.1 Pro to Windows 10 - it will NOT activate Windows 10 Pro - it will only cause the upgrade to Windows 10 Pro.
3. After the upgrade, go back to Settings and activation screen and enter your Windows 7 Pro product key, which should activate your Windows 10 Pro (you have to be on version 1511, build 10586 - also known as November update - of Windows 10).
If step 3 fails for some reason, you will have to re-install your Windows 10 Home - either a new clean install, or restore from a backup image.
Thank you for your response.
Backup Utility that one can use to make back ups of C:\. If future backups are made to the same folder then the utility makes incremental backup.
Now, the issues:
Why the utility does not backup D:\ partition where Lenovo has System Drivers beats me.
Backups cannot be made on external HDD greater than 2TB even on Win-10 systems. Why? Why?
Of course, I digress.
But will be making a system back up of C:\ using Lenovo utility. Make a full backup of D:\ that has all drives.
Install Macrium Reflect and make another backup just in case of whole system. Can never be too careful :-)
Will need to look at how to manually trigger the update to Win-10. I thought it comes as a windows update. Unless I misunderstood you and you meant to download Win-10 iso and do a complete Win-10 install.
Thanks again for your input.
If you want to clean install Windows 10, then you would boot from the WIndows 10 USB/DVD.
Thank you for your assistance. Afraid I'm a bit lost on the exact steps now to follow:
Earlier it was suggested to upgrade from Win-10 Home to Pro using generic key, then enter my Win-7 Pro key to try and activate Win-10 Pro.
Now, with the need to use specific version, it seems that I need to
- first install Win-7Pro on laptop with Win-10Home,
- download the specific version of Win-10Pro from MS
- then upgrade to Win-10 Pro while running Win-7
Please let me know if I misunderstood.
Thanks again for your help.
Getting closer. already made my backups and will be downloading Win-10 iso soon.
can I use an iso from a friend who has MSDN account (he won't provide any license, just an iso)? The iso he has says version 1511 but am not sure about build.
Simple question for you, IF your windows 7 you have right now ON your laptop IS Windows 7 Pro, then download Windows 10 Pro. What you should be doing is upgrading your Windows OS to the SAME version of Windows you ARE Running Now.
Home for Home, Pro for Pro. Its that simple.
Here is the link for down loading Windows 10, read the instructions, and then download the Windows 10 version you are actually running right now on your laptop. I would suggest you download the Windows 10 version from Tech Bench.
Here is the link to read instructions, and download link also.
Windows 10 ISO Download
Enter the Windows 10 Pro generic product key:
When it is done upgrading to Pro, it will not be activated. To activate it go back to the same activation screen and click on change product key again and enter your Windows 7 Pro product key to activate it.
