Cannot upgrade Windows10 from Home to Pro

I've purchased the Windows 10 Pro key and tried to Change the key on my Windows Home Single Language. However, it told that this key or digital license is not valid.

I've tried to overcome this by entering the Generic Windows 10 key to change it to my own later and upgrade starts, but fails with attached error message

If I Click Troubleshoot



As you can see, there's no troubleshoot button and system says that my key can't be used on this copy of Windows whatever it means.

The current Windows version is pre-installed by laptop manufacturer.

Attempt to reinstall Windows failed with the similar error message

Hi,
Windows Home Single Language edition is different with Windows Home edition, which cannot upgrade to Windows 10 Pro edition directly via change generic Pro product key.
You need to clean install Windows 10 Pro edition then use your valid product key to activate system.
Or clean install Windows 10 Home edition(not Home Single Language), upgrade by Pro generic product key, next, activate by valid Pro license.
Please note: backup your important personal data before clean install. Download Windows 10 ISO file from here:

Thanks, that did the trick.

Now I have the similar situation with another Win Home SL machine, but that's the different topic: it just fails to install updated version from MS Store

Hello,

Not sure which generic key you've already tried. I suggest you to try upgrading using generic product key mentioned in this step-by-step guide:

Once upgraded, you can activate Pro edition using your own genuine product key.

Hope this helps!

In that case, I suggest you to backup your content and directly make clean install of Windows 10 Pro:

After clean install of Pro edition, you can activate it with your genuine product key.

I had, same issue the key i bought cannot be activated. The solution that works for me is, i do "windows update", with so many restart. After windows shows "You're up to date". Try goto change product key, the key will be activated.
