I am logged in as me and I am an Administrator. Is the Administrator account different then a user with Administrative privileges?
Sorry for the delay.
Most times, being an Administrator = being THE Administrator, but they aren't exactly the same. I no longer have a Windows 10 PC, so you'll need to research how to activate the Administrator Account and then log in as the Administrator.
You'll then need to see if you can schedule your task as the Administrator. If you can, there's something wrong with the admin-equivalent permissions on your user account. If you still can't set up your user task as the Administrator, you'll probably need to research the ways how to take ownership of files and directories.
