For your convenience, I’ve decided to provide some tips for computer repairs and upgrades in the Sydney area. 1st one is “How to upgrade Windows 10 Home to Windows 10 Pro”.

There are a few differences between Windows 10 Home and Pro. The biggest difference is Windows 10 Home cannot join any domain network. So, if you plan to use your Windows 10 computer to join any domain network that runs under Server – Client (for example to join abccompany.com.au network), your Windows version must be Windows 10 Pro or Enterprise/Education editions.

OK, they say “if you have an old product key from Windows 7 Pro, Windows 7 Ultimate, or Windows 8/8.1 Pro you can use that to upgrade from Windows 10 Home to Windows 10 Pro. That covers you either for a fresh installation, if you’re setting up a new system, or to enable the upgrade on an existing rig”.

This is not quite true. I’ve tested with Windows 10 Home HP Laptop changing product key (which was never been used for Windows 10 upgrade) Windows 7 Professional key for Windows 10 Pro update. The result was that no matter how many times I tried to enter a legitimate key, the Windows activation system returned an error.

There are 2 scenarios;

1. Scenario 1
Branded computers such as HP, Lenovo, ASUS and Acer were released after Windows 10 was introduced.

Usually, those branded computers have a hard coded OEM_COA (Original Equipment Manufacturer_Certificate Of Authenticity) in the computer’s BIOS and in all cases it only activates Windows 10 Home and not Pro.

If that is the case, a fresh install of Windows 10 from either the DVD base or the USB base, never asks you to input any Windows 10 product key in the process, just install Windows 10 Home.

After starting Windows 10 Home, if you are lucky, adding Windows 7/8/8.1 Pro (plus Ultimate in the case of Windows 7), may activate Windows 10 Pro and go through the Home to Pro updating process. If you are not lucky, activation fails with an error.

 

If you see the above screen, only way to upgrade Home to Pro is to purchase Windows 10 Pro key.

2. Scenario 2
Branded computers, as above, were released before Windows 10 was introduced to the market comes with pre-installed Windows 7, 8, and 8.1 Home. You updated to Windows 10 Home using the Microsoft Free Upgrade Offer. If you remember, the upgrade was free for all users. To get Windows 10 Pro, back up the Windows 10 Home hard drive image to an external drive. Erase everything on the internal hard drive when you install Windows 10 (Pro). When prompted to put product key, input Windows 7/8/8.1 Pro (plus Ultimate in case of Windows 7) in a box then after some time, Windows 10 Pro installation will start.

After confirming that Windows 10 Pro is activated (needs an Internet connection in the process), restore backup saved on the external drive.

Start your PC with a installed Windows 10 Home, then change the key with:
VK7JG-NPHTM-C97JM-9MPGT-3V66T (Generic Windows 10 Pro Retail Key).

Then, your PC will be upgraded from Windows 10 Home to Pro.

Whatever method you want to apply, please make sure you backup the entire system drive image to any external media in case the upgrade does not work.

Once again, never purchase a branded computer (either a laptop or desktop) with Windows 10 Home hard coded in the BIOS if your plan to use it a company or organisation network client computer. You are asking only for troubles.
