Windows 10: Windows activation upgrade

Hey, can anyone give me a hand?

I'm currently trying to change my product activation from windows 10 home to -> windows 10 pro but after entering my license key is throwing me this error message:






I'm on internet and is not really related to my internet connection.


I found this article : https://www.diskgenius.com/how-to/fix-error-code-0x80070057.php

but didn't work for me either.


Can someone help me out?

:)

 

Activating Windows 10 after upgrade

Hi Varghese,

Thank you for posting your reply. Apologize for the delay in response.

I would like to inform that as you are using an Genuine Windows 7 in your system,
Windows 10 will automatically be activated online and create a digital entitlement for your device.

If you still face issues with Activation after upgrading to Windows 10, suggest you to activate the Operating System through phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
• Call the Toll-Free number provided on top and can activate via phone.

Hope the information is helpful. Do get back to us for any other assistance.

If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

• Go to Start
  
  , then select Settings > Update & security > Activation.
• Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.
  
  Note
  • This only applies if you haven't made changes to the hardware for your device.

or you could hack it with a crack but please note this is always risky and you don't know what's in the hack

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
