添加Windows Defender例外的方法是：打開Windows安全中心，進(jìn)入病毒和威脅防護設(shè)置，添加排除項。具體步驟為：1. 打開Windows安全中心；2. 進(jìn)入“病毒與威脅防護”；3. 點擊“管理設(shè)置”；4. 在“排除項”部分點擊“添加或刪除排除項”；5. 選擇要添加的排除類型（文件、文件夾、文件類型或進(jìn)程），並指定路徑。共有四種例外類型：文件、文件夾、文件類型和進(jìn)程。常見問題包括需使用管理員賬戶、正確輸入路徑、可能需要重啟程序或系統(tǒng)。使用例外時應(yīng)謹(jǐn)慎，僅排除可信項目，避免廣泛排除如*.exe等不安全操作。

Adding an exception to Windows Defender is something you might need to do if a legitimate file or program keeps getting flagged as a threat. This doesn't mean turning off Defender completely — it just tells the system to leave certain files, folders, or apps alone.

When You'd Want to Add an Exception

You usually add exceptions when:

• A trusted app gets blocked or quarantined
• A custom script or development tool triggers false positives
• You're running software from less common sources that you've verified safe

Defender is good at what it does, but sometimes it's overprotective. That's where exceptions come in handy.

How to Add an Exception in Windows Defender (Step by Step)

To whitelist something in Windows Security (which includes Defender), here's how:

1. Open Windows Security

   
   • You can find it by searching “Windows Security” in the Start menu or taskbar search box.

2. Go to Virus & threat protection

3. Click on Manage settings under "Virus & threat protection settings"

4. Scroll down to Exclusions and click Add or remove exclusions

5. Click Add an exclusion , then choose what type of exclusion you want:

   • File
   • Folder
   • File type
   • Process

6. Browse or enter the path, then confirm.

That's basically it. Once added, Windows Defender will no longer scan or block that specific item.

Types of Exceptions You Can Add

There are four types of exclusions available:

• File : If one specific file keeps getting blocked, exclude just that file.
• Folder : Useful for excluding an entire directory — like a dev folder with multiple scripts.
• File type : Exclude all files with a certain extension (eg, .exe , .bat ). Use this carefully.
• Process : Exclude a running program by its executable path.

Each option works a bit differently, so pick the one that best fits your situation.

Common Issues When Adding Exceptions

Sometimes things don't work right away. Here are a few gotchas:

• Make sure you're using an admin account.
• If you're excluding a folder, double-check that the path is correct.
• Some exclusions may not apply immediately — restart the app or even the system if needed.
• Real-time protection needs to be on for exclusions to work properly.

Also, keep in mind: just because something is excluded doesn't mean it's safe. Only exclude items you trust.

Exceptions Are Easy, But Use Them Wisely

It's not hard to set up exceptions, but it's easy to misuse them. Avoid adding too many or broad exclusions like *.exe . Stick to only what you know is safe.

基本上就這些。
