1. Open Windows Powershell.
    To do this, type Powershell in the Windows Start menu command box.
  2. Type Get-FileHash followed by a space.
  3. Drag the downloaded ZIP file onto the Windows Powershell window after the Get-FileHash command.
    This inserts the path after the command, to look similar to the following text:

 

PS C:\Users\UserName> Get-fileHash C:\Users\UserName\Downloads\cdq2019s14_Windows.zip

   4. Press Enter.
This results in output similar to the following:
PS C:\Users\UserName> Get-FileHash C:\Users\UserName\Downloads\cdq20191s14_Windows.zip

   5. Compare the calculated hash value with the original hash value.

         You should not have to look too closely, as there will be a massive difference in the checksum even if there is only a tiny difference in the underlying file.
