Win10 修改 hosts 檔案翻牆/屏蔽網址後導致瀏覽異常？將檔案還原為原版標準內容即可解決。以下為 Win10 官方預設 hosts 完整內容。

原版標準內容

1. 用記事本開啟 C:\Windows\System32\drivers\etc\hosts (需管理員權限)。
2. 清空全部內容，貼入以下標準內容：

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#       102.54.94.97     rhino.acme.com     # source server
#       38.25.63.10      x.acme.com         # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1       localhost
# ::1             localhost

3. 存檔 (Ctrl+S) → 關閉記事本。

注意：修改 hosts 需管理員權限，建議以系統管理員身分開啟記事本再開啟檔案編輯，或複製到桌面編輯存檔後覆蓋回原位置。
