Hi Jim -
I'm Kevin B. Independent advisor and a Windows user like you. I do apologize for the inconvenience that you experiencing right now, let me help you sort things out.
Why are you trying to reactivate windows? Did you reinstall windows on your computer?
Did the windows came pre-installed or do you have a product key that you use to activate windows?
Error code 0xc004f213 usually indicates that there are internal errors found on your computer.
Kindly follow the steps below and check if it will resolve the issue
Run a system file checker to verify the integrity of windows system files on your computer making sure that there are no corrupted files on your windows.
Perform SFC Scan and Repair Windows Image
-This process will perform scan for any corrupted system files or integrity violation and will attempt to repair it along with the Windows Image.
- Open command prompt with administrator access
- Type each command below and wait until scan is completed.
SFC /scannow
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
Quick note: While the command is running, it's expected to see the process stuck at 20 or 40 percent. After a few minutes, the process will complete successfully.
Once you complete the steps, the Deployment Image Servicing and Management tool will connect to the Windows Update servers to download and replace any damaged files in the local image for Windows 10 as necessary.
- Close the command prompt.
After the scan completes, kindly run the activation troubleshooter to identify and fix the problem

Kindly keep me posted of the result
Hope this will help and have a bless day!
Thanks.
