Cannot open file"C:尀WINDOWS尀system32尀driver尀etc尀hosts系统找不到制定的文件

从其他电脑上复制一个hosts回来，放到你电脑上的C:\WINDOWS\system32\driver\etc\目录下。
或者，打开这个目录，新建记事本，打开记事本，把下面内容复制进取，保存退出。
然后重命名“新建 文本文档.txt”为“hosts”，注意去掉后缀名！

# 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

127.0.0.1 localhost
127.0.0.1
