Sir, I brought Acer computer with preinstalled Windows 8. (x64 bit) Later I upgraded to Windows 8.1 Single Language. The manufacturer didn’t provide any Windows CD, and also I did not create any recovery CD. Due to virus, I had to format my system with a Windows 8 CD. Before formatting I had noted Windows 8.1 SL Product Key. Everything went on well but after installation, I noticed that Windows 8.1 Pro. was installed and the system asks a production key to activate Windows. But I have only Windows 8.1 Single Language production key, which is not matching with Windows 8.1 Pro. Please let me now how to solve the problem. Can I download Windows 8.1 SL and use the existing Win8.1SL product key?

You can only install Windows 8.1 Core SL if your laptop came with the same. If you want Pro, you want to buy product key for that version separately from Microsoft store or retail stores.

Like visruth posted, go here, Create installation media for Windows 8.1 - Windows Help and download Windows 8.1 Single language. Then reinstall Windows with that install media. It will read and use 8.0 keys and 8.1 keys, even OEM embedded keys. How did you install Pro without entering a product code?
