Hello,
It's common for schools to block access to certain websites, especially games and streaming services, to help students focus and keep the network safe. Instead of trying to bypass these blocks, it’s a good idea to talk to a teacher or school IT staff if there’s a specific site you need. It is up to them to determine if it can be unblocked.
Also, please know that this forum is for users 13 years or older. If you are under that age, it is best to have your parents post your questions. (Code of conduct can be reviewed here: https://answers.microsoft.com/en-us/page/faq#faqCodeConduct ) In the code of conduct, it also asks that you don't post same or similar questions. So I would suggest you do not write about this everyone, as the moderators will delete any repetitive threads.
