Windows 10: Product key error

So I have Windows 10 on my computer for about 4 years and I need help with my product key. Ive accidently changed the product key not knowing that the product key that I accidently changed to didn't activate the Laptop. I tried changing the product key back, but every time I get an error code 0x004f050 for some reason. If needed, I can send you the last 5 numbers/letters of the product key. Also, I've tried doing 2 hard resets because I thought I could then activate my Windows with another key.More detailed info:I first had Windows 10 home, now unactivated Windows 10 pro. I don't know how t

Hi Piyush,

Thank you for posting your reply.

I suggest you to activate the copy of Windows via phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select your Region/Country.
• Select the Phone Activation option, and hold on for a real person.

Hope the information is helpful.

Regards
