- **Computer 2**: a client computer from your corporate network. It is shadow-copied to create a VM that can be added to the PoC environment, enabling you to test a mirror image of a computer on your network. If you do not have a computer to use for this simulation, you can download an evaluation VHD and use it to represent this computer.

They do this to get easier access to your data, to install malware, or to otherwise exploit your data, identity, and devices. Tamper Protection helps prevent this from occurring.

Tamper protection essentially locks Windows Defender Antivirus and prevents your security settings from being changed through apps and methods like these:
- Configuring settings in Registry Editor on your Windows machine
- Changing settings through PowerShell cmdlets
- Editing or removing security settings through group policies
- and so on.
Tamper Protection doesn't prevent you from viewing your security settings. And, Tamper Protection doesn't affect how third-party antivirus apps register with the Windows Security app. If your organization is using Windows 10 Enterprise E5, individual users can't change the Tamper Protection setting; this is managed by your security team.
