之前让同事架设了一个openvpn, 后来同事离职, 用命令注销账号, 确老是报错, 后来不断有新账号加入需要, 后来想要是有个web页面去管理就好了,就在github上搜, 后来找到了这个项目: https://github.com/Chocobozzz/OpenVPN-Admin 正符合需要, 于是就开始clone下来安装. 依次输入命令:

我用电脑通常是上午开了就会到晚上睡觉前才关的，习惯工作时打开一大坨软件备用，而且经常工作一段时间就会休息一下——吃饭/喝杯茶/上厕所/找个地方发呆/出街去朋友店里坐一下…然后回来继续，偶尔敲的代码会忘记 Save 回来时继续敲。 但是……不知道什么时候开始，Windows 10 自己后台更新后会弹出重启倒计时，如果你没按选项就会在指定时间内自动重启。所以问题就来了：好几次刚好我出去或者家里吃晚饭时遇到自动更新完需要重启，等我回来时 Windows 10 停在登录界面，尼王马—— 我未保存的代码呢？ 刚才还没看完的网页呢？ 休息时看到一半的视频呢？ 正在下载的文件才下了一半… …… 于是去找设置，竟然没有“有更新通知我”类似的设置了，有个工作时间内不要重启的功能，但尼王马只能设置1-12小时，微软你不知道中国的码农工作时间很长的么？想用 1:00-24:00 曲线避开重启都不行！ 放 G 搜，还真多人遇到，解决方法是通过修改注册表找回原来的设置，我嫌太麻烦，后来用了“禁用Reboot任务计划”来实现，方法是： 在开始按钮右键（Win键+X）> 弹出的菜单中选择“计算机管理” 在打开的“计算机管理”窗口中依次展开定位至以下路径：系统工具 – 任务计划程序 – 任务计划程序库 – Microsoft – Windows – UpdateOrchestrator 在右侧窗格中即可看到 Reboot 任务计划，右键点击 Reboot 任务计划，选择“禁用”。如下图： 微软你继续微软不行么，这坑人的微硬有意思么？ —- 2016.12.05 更新：我现在用的方法是通过组策略来禁止自动更新（要使用组策略只能是 Windwos 10专业版、企业版、教育版吧） Win+R 键打开运行窗口，输入 gpedit.msc 确定打开组策略 然后打开通过“计算器配置”……看图吧
