Activation error 0x803fa067 windows 10
3 days ago I bought a new key for windows 10 home because I upgraded my hardware.
When I use the key it gives the error 0x803fa067.
I searched all over the web and also tried the phone activation, nothing worked.

Did you boot your pc???.... if yes then your seller would have provided you a windows DVD the original one for backup and even a graphic installer if your computer support integrated graphics.

Thanks for your help.
