Today I've installed my first Windows 2019 server ( I'm a lucky guy I know ... ) and I've got error 0x80070490 during the activation process
because I was sure the serial was correct I tried again from command line with the following command:
c:\windows\system32\slmgr.vbs /ipk your-windows-license-here
and it worked !
Another mystery in MS software fixed! I really love to work with my Linux server !!!!
