Hello , I am building a pc that will be used also by my young nephew. He likes to download all the bad stuff from the internet no matter how many advices he receives . I don't want to limit his actions nor do I want to delete all of his downloads and installations each time he exits / logs off. I was wondering if there is a way to constantly keep a user in a sandboxed / virtualized account isolated from other users; A sandbox/Virtual environment that won't be re-initialized each time the user logs on or reboots but will let the user building up his own messy account without affecting other user accounts. Thank you for any advice or suggestion.
