I have an elderly relative who I have installed Chrome for on a Windows 8 and Windows 7 box. Every few weeks I get a complaint that the web browser is not working. I go in, and there are a dozen or so Chrome extensions that have been installed; all of which are nuisances for redirecting search, shopping, etc. None are needed. I go through, uncheck all of them to disable them, and all is well for another few weeks.
Is there any way to lock down Chrome through a registry or other setting such that extensions are impossible to be installed? I don't just want to make it hard - I want it impossible. Even if there were an "are you sure" prompt, this relative would click through it and install it.
I want this relative to have a vanilla version of Chrome each time it is opened. Any extensions should be automatically blocked, with no option given to allow or enable them. A hardened version of Chrome, essentially, that is elderly-proof.
