Disabling Windows Defender can be necessary in certain cases, like when you're using a third-party antivirus and want to avoid conflicts. But keep in mind that turning it off leaves your system more exposed if there's no replacement protection in place.

Why You Might Want to Disable It

Some users disable Windows Defender because they're running another antivirus program. Running two at the same time can cause slowdowns or false alerts. Others might find its real-time scanning intrusive during gaming or heavy workloads. Whatever the reason, just make sure you understand the trade-offs before moving forward.

Using Group Policy (Best for Pro Versions)

If you're on Windows 10 Pro, 11 Pro, or any business version, this method is solid:

• Open Run by pressing Win R , type gpedit.msc , and hit Enter.
• Go to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus .
• Double-click on Turn off Microsoft Defender Antivirus .
• Set it to Enabled , then click Apply and OK.

This method fully disables the service, including background scanning. Just note that it won't work on Windows Home editions.

Editing the Registry (For All Versions)

If you're on Home edition or GP isn't an option:

• Press Win R , type regedit , and open the Registry Editor.
• Navigate to:
  HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
• Create a new DWORD (32-bit) Value named DisableAntiSpyware and set it to 1 .

This stops Defender from running and blocks most of its features. Be careful with registry edits — a mistake can cause system issues.

Temporarily Pausing Through Settings

Sometimes you don't need to fully disable it — just pause for a while:

• Open Settings > Privacy & Security > Windows Security .
• Click Virus & threat protection .
• Under Virus & threat protection settings , click Manage settings .
• Toggle off Real-time protection .

This only turns off active scanning but doesn't stop Defender completely. Useful for short-term tasks like installing software or troubleshooting.

Do one of these methods fit your situation? If you're not replacing Defender with something else, consider leaving it on — even partial protection is better than none.基本上就這些。
