Microsoft Toolkit是一款免费的Windows8激活/win8激活工具和Office2010/2013激活工具，是由Office2010 Toolkit(Office2010激活工具)同一个作者制作。运行Microsoft Toolkit，点击界面右下角的Office图标进入Office Toolkit界面，点击Windows图标进入Windows Toolkit界面，对应激活Office2013和Windows8系统。
老版本则支持win7和office2010
1 选择Microsoft Toolkit并“以管理身份运行”。
2 点击Office或Windows产品定义KMS服务器后续的 *** 作步骤。
3 进入第二个选项卡“Activation”，并选择Tool *** 作方法“AutoKMS”
4 安装KMS服务，并在安装成功后点击“EZ-Activator”进行注册 *** 作。
5 安装成功后，显示结果
