Currently I've installed windows 10. But I cannot activate it.
slmgr /ipk "key"
but it return error code 0xC004F074
How can I solve it?
Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.
This issue might occur if the software licensing service reported the product could not be activated, no key management service (KMS)
could not be contacted.
Try the below methods:
Follow the on screen directions to activate over phone.

How to activate a Microsoft product by using Microsoft Product Activation Center:
System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue.
Refer to these steps to perform a SFC scan:
Windows key + X, select Command prompt (Admin) to bring up elevated command prompt
b) In the command prompt type the following command:
sfc/scannow and press enter
c) After the scan, restart the computer and try to activate online first. If the issue persists, then try to activate over phone.
If the issue still persists, I would suggest you to contact the Microsoft Customer Support team for further assistance with this issue.
