AFAIU, 'takeown' is different from 'chown', in that it only allows to
change the file's owner to either the current user or the
Administrators group, it doesn't allow you to change the ownership to
any other user except one of those two.  Also, I think the command
requires elevation, doesn't it (thus you mention "admin privileges")?

So I'm not sure that command is a good replacement for 'chown', but
maybe you have something in mind I'm missing?

Thanks.
