KMS激活的过程简单说就是：欲激活的电脑向KMS服务器请求，KMS服务器做出回应同意激活。
KMS激活软件是将KMS服务器用一段代码来模拟，做成一个可执行的程序（即所谓的KMS伺服器）。KMS激活软件在激活Windows或Office的时候，首先启动这个KMS服务器，然后再执行KMS激活的相关命令，向服务器请求激活就可以大功告成了，整个过程十分简单。
方法有很多种，举例：
1、下载软件，运行后模拟KMS服务器。
2、自建服务器。很多第三方路由器固件都有。
上面搭建好的KMS服务器，就可以使网络上的朋友用来激活Windows10/8.1以及Office 2016/2013等VL版本。具体激活需要的命令如下，以激活Windows10为例：
1、如果激活Windows 10 Professional，首先需要KMS密钥，Win10专业版对应的KMS密钥为W269N-WFGWX-YVC9B-4J6C9-T83GX，激活其他版本Windows替换其他的密钥（密钥：https://technet.microsoft.com/en-us/library/jj612867.aspx）。那么以管理员身份运行“命令提示符”，键入命令：slmgr -ipk W269N-WFGWX-YVC9B-4J6C9-T83GX；
2、键入命令：slmgr -skms 192.168.2.254；
3、键入命令：slmgr -ato 即可大功告成！
180天后需重新激活。
slmgr -ipk W3GGN-FT8W3-Y4M27-J84CP-Q3VJ9 slmgr -skms 192.168.2.254 slmgr -ato
