• windows本地浏览器没有启动 explorer do not start up on windows

  DG works：
  打开系统组策略编辑器就是gpedit.msc，找到“用户配置”——“Windows设置”项——脚本（注销与登录）——登录（添加，将脚本路径改为Explorer.exe的路径，如：C:\windows\Explorer.exe）即可。这样在登录时系统会再加载一次Explorer.exe就可以显示出桌面了。但也有如我的状况，gpedit.msc打不开。

• windows10和Ubuntu双系统，时间不对

  2016-11-10

  tech

  原博文

  windows10和ubuntu16.04双系统，仍然出现了喜闻乐见的老问题，装完后，在windows下时区不对，之前的老办法是：

  sudo gedit /etc/default/rcS
  utc=yes 改成 utc=no
  

  然而并没有什么效果，ubuntu16.04里面根本就没有utc这一项！
  后来谷歌了半天找到了一个完美解决办法：
  先在ubuntu下更新一下时间，确保时间无误：

  sudo apt-get install ntpdate
  sudo ntpdate time.windows.com
  

  然后将时间更新到硬件上：

  sudo hwclock --localtime --systohc
  

  重新进入windows10，发现时间恢复正常了！

  新博文

  但是在ubuntu24.04中，更新：

  简单来说，在Ubuntu24.04中，hwclock已经被淘汰了，并采用了timedatectl去代替它。 因此我们可以在联网状态中使用下列代码实现Ubuntu与Windows的时间同步。

  sudo timedatectl set-local-rtc 1
