Hello,
Thanks for posting in the Microsoft community.
I understand that your Windows 11 PC began showing restrictions and changes after connecting to your school’s Wi-Fi. It sounds like it may have automatically enrolled into the school’s device management system, which can apply settings such as app restrictions, policy enforcement, or even enable features like “Windows To Go.” Let's work through this together.
To help resolve this, I recommend reaching out to your school’s IT department. They’ll be in the best position to:
- Confirm if your device was enrolled into their system
- Remove it from their management
- Help restore access to your apps and settings
Until then, try to avoid reconnecting to the school network to prevent additional policies from syncing.
I hope this helps. Please let me know if you need any further assistance.
Best wishes,
