Here is a procedure to check for SHA256 integrity of a downloaded file or installer: 
- Open Windows PowerShell. For example, type PowerShell in the Windows start menu command box.
- Type Get-FileHash followed by a space.
- Drag the downloaded file or installer onto the Windows PowerShell window after the Get-FileHash command and the space. Alternatively, enter the full path to the file or installer in double quotes after the space. For example:
- Press Enter. The output is similar to the following:
- Compare the PowerShell calculated value with the hash value provided. If the Hash values match the file integrity is ok.
