It is extremely difficult if not impossible to bypass Screen Time restrictions under Windows 10. This is necessary when a child account is locked due to Screen Time restrictions, yet you want to enable it temporarily. For example, your daughter needs 5 minutes to send an urgent item to the printer. Further, say that you as the parent need to leave the house and don't have time to sit around and wait for some email from Microsoft to approve an unblock request. Under Windows 8, a parent or administrator could use their login password to give the child more time. But there is no facility for doing this under Windows 10. You can't unblock a child account even by entering a parent or administrator password.
You might think by going into to the family safety website and changing the settings there, they would take effect immediately. Well, I understand it takes a few seconds or perhaps a minute to propagate parent setting changes over to the target computer. And on one occasion, I recall it happening right away. But this usually does not happen right away.
Another option is for the child to request more time by clicking a button labeled "Get More Time." Well, this doesn't work right away either. Many minutes or even hours pass before the parent receives an email message from this system. I don't know just how long because I have simply given up and gone on with my life, which as a parent is filled with many things.
Why can't the system simply send an email message with the unblock request right away? I can wait a minute or two but longer than that? Come on, this is a multi-billion dollar multi-national computer industry giant. If you want me to rely on your products they need to be rely-able.
