# Prevent security settings changes with tamper protection
# Protect security settings with Tamper Protection
**Applies to:**
- Windows 10
Tamper Protection helps prevent malicious apps from changing important security settings. These settings include:
## Overview
- Real-time protection
- Cloud-delivered protection
- IOfficeAntivirus (IOAV)
- Behavior monitoring
During some kinds of cyber attacks, bad actors try to disable security features, such as anti-virus protection, on your machines. 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.
With Tamper Protection, malicious apps are prevented from taking actions like these:
- Disabling virus and threat protection
- Disabling real-time protection
- Turning off behavior monitoring
- Disabling antivirus (such as IOfficeAntivirus (IOAV))
- Disabling cloud-delivered protection
- Removing security intelligence updates
With Tamper Protection set to **On**, you can still change these settings in the Windows Security app. The following apps and methods can't change these settings:
## How it works
- Mobile device management (MDM) apps like Intune
- Enterprise configuration management apps like System Center Configuration Manager (SCCM)
- Command line instruction MpCmdRun.exe -removedefinitions -dynamicsignatures
- Windows System Image Manager (Windows SIM) settings DisableAntiSpyware and DisableAntiMalware (used in Windows unattended setup)
- Group Policy
- Other Windows Management Instrumentation (WMI) apps
Tamper Protection essentially locks Microsoft Defender 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.
The Tamper Protection setting doesn't affect how third party antivirus apps register with the Windows Security app.
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.
On computers running Windows 10 Enterprise E5, users can't change the Tamper Protection setting.
### What do you want to do?
Tamper Protection is set to **On** by default. If you set Tamper Protection to **Off**, you will see a yellow warning in the Windows Security app under **Virus & Threat Protection**.

## Turn Tamper Protection on (or off) for an individual machine
If you are a home user, or you are not subject to settings managed by a security team, you can use the Windows Security app to turn Tamper Protection on or off. You must have appropriate admin permissions on your machine to perform the following task.
1. Click **Start**, and start typing *Defender*. In the search results, select **Windows Security**.
2. Select **Virus & threat protection** > **Virus & threat protection settings**.
1. Open the Windows Security app by clicking the shield icon in the task bar or searching the start menu for **Defender**.
2. Select **Virus & threat protection**, then select **Virus & threat protection settings**.
3. Set **Tamper Protection** to **On** or **Off**.

>To help ensure that Tamper Protection doesnt interfere with third-party security products or enterprise installation scripts that modify these settings, go to **Windows Security** and update **Security intelligence** to version 1.287.60.0 or later.
