Bypassing Sophos Endpoint Application Control

So my school uses a program called Sophos Endpoint to block use of certain applications. An example of one such application is 7-Zip. When I try to load an application that is blocked, it gives me a pop-up message saying “Use of application [blank] is disabled by your administrator.” I looked into this and learned that this part of the Sophos program is entitled Application Control.

When Sophos isn’t up, when I try and run one of these applications, I get a message saying “Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access them,” which makes me think that they may have more measures set up.

If someone can help me get past either of these, it would be greatly appreciated.
