Get File Hash on Windows PowerShell

My instructions are for Windows 10, but I am sure it will work on every Windows wirh powershell.
It could be useful for security updates and suspicious executables.
Open PowerShell Windows key->Type PowerShell
Move to the folder where file are placed
cd c:\folder
where your file are located
Get-FileHash .\filename.extension -Algorithm SHA256
or 
Get-FileHash .\filename.extension -Algorithm SHA1
Lets say wou want to check Gimp downloaded in c:\temp
Get-FileHash -Path c:\temp\gimp-2.10.0-setup-2.exe -Algorithm SHA256

Thats it.
