I came across this method for helping each other . Immediately thought of Graham! Phone at a convenient time, get him to login as the administrator, then open browser, maybe IE. (I'm assuming you both have computers connected to the internet.) One of you then types https://join.me/ and then clicks "Share". The other person then types the link provided by this process into their browser and, as a consquence, gets to "see" the others computer. It doesn't really matter who initiates this process, as control of either computer can be passed to the other (by clicking "Share control"). This is the easiest way I know of to demonstrate something or take control of another computer. We trust each other , don't we? What is the command for Format C: ? NB Andrew, not a mention of health.
