Step 1: Purchase a low cost Windows license from here.. Apparently, the ‘Retail’ key is more reliable than the ‘OEM’ version of the key.
Step 2: On the machine to be upgraded, start Command Prompt with admin privileges. Run this: changepk.exe /productkey VK7JG-NPHTM-C97JM-9MPGT-3V66T. This will require you to reboot the machine and install the files necessary to get you into Professional license. If you are not going to buy a license and are okay without activation, you can use it. But if you bought a license go to the next step.
