可能时不时需要装个系统，虚拟机里随便玩玩，也就没有正版系统这回事了。可以用别人做好的工具，也可以直接用系统命令激活，以下方法收录备用。

方法步骤

1、建议从微软官网下载评估版安装系统，不考虑安全问题不想从官网下载其他任何地方下载其实都可以的。

2、开始》运行》CMD(最好以管理员身份运行)》输入 DISM /online /Get-CurrentEdition （可直接复制粘贴，然后回车），看你的当前版本是什么。

如果是评估版，例如 Standard，把 ServerStandardEval 中的 Eval 这四个字母去掉，就是你的当前版本。如下所示，则当前版本就是 ServerStandard。

3、然后输入并运行以下命令：

DISM /online /Set-Edition:EDITION ID /ProductKey:X-X-X-X-X /AcceptEula

这里 ServerStandard 就是查出来的EDITION ID，将实际查出来的 Current Edition 如实填入上方命令对应位置，ProductKey 后面的序列号见附录。

4、重启
