不小心删除了C:\WINDOWS\system32\drivers\etc\hosts怎么办

没事，需要的自己建一个就行了。具体做法就是：用记事本新建一个文件，然后另存为，保存类型选所有文件，命名为hosts，注意不要加任何后缀，再放到原来的位置（C:\WINDOWS\system32\drivers\etc）就行了。要与原来文件一模一样就把下面的内容加进去：
# Copyright (c) 1993-1999 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
