Checking the hash of a file you’ve downloaded from the internet is very good practice. It’s a way to ensure the file you’re downloading hasn’t been tampered with, according to the hash provided on the site you’re downloading from.

Windows server administration is not without those DOH! moments. How is it that I, the administrator cannot change the permissions on a folder?
The easiest way to fix this is to take ownership of the folder using the TAKEOWN command. Takeown is a tool that will allow an administrator to recover access to a file or folder that was denied by reassigning ownership. Open the command prompt and run as administrator.
takeown /f F:\FolderName /r /d y
/f Specify the file name or directory
/r Recurse through all directories and sub directories
