vs2017试用延长期已到
Did you know that you can install Windows 7 without any license key and use it for 30 days? What you might not know is that you can also extend that trial mode to 120 days, without requiring a key.
您是否知道无需任何许可证密钥即可安装Windows 7，并可以使用30天？ 您可能不知道的是，您还可以将该试用模式延长至120天，而无需输入密钥。
The basic way this works is that at the end of the 30 days, you’ll need to run a small command and reboot your computer, at which point you’ll have 30 more days, up to a maximum of 120 days. This trick should work regardless of where you got your copy of Windows 7 from.
这种工作的基本方式是，在30天结束时，您将需要运行一个小命令并重新启动计算机，这时您将还有30天，最多120天。 无论从何处获得Windows 7副本，此技巧都应起作用。
