(KMS is a service for activating Microsoft products on a local network without connecting to Microsoft,
Both physical machines and virtual machines can be activated (but the number of machines must meet or exceed the activation threshold,
The server series is 5, the Windows series is 25), and the KMS client installs the KMS client key
(Generic Volume License Key, GVLK) by using DNS or static configuration to locate the KMS server,
Then use remote procedure call (RPC) to contact it and try to activate it, although KMS greatly reduces
It saves the activation work of the computer administrator, but the official KMS service still has many restrictions,
For this reason, unlimited KMS service agents have also appeared on the market, such as py-kms, vlmcsd, etc.
Activation steps: Download the activation script according to your own system, and then right-click to run the script as an administrator.
If you do not know the system version, you can use Win+R, enter cmd to run, and then enter slmgr /dlv in the command window to view the version.
After the system is activated using KMS, the validity period is 180 days. The system will connect to the KMS server every 7 days to obtain the latest authorization.
The activation period will then be reset to 180 days. As long as the KMS activation server is not suspended, the activation status will continue automatically without manual intervention.)
