Step 1.1: Run Command Prompt app as administrator.
Click on the start button, search for “cmd” then run it with admin rights.

Step 1.2: Install KMS client key.

Use the command “slmgr /ipk kmsclientkey” to install a license key (kmsclientkey is the activation key that corresponds to your Windows edition).
The following is the list of Windows 11 Volume license keys.

"slmgr /ipk kmsclientkey W269N-WFGWX-YVC9B-4J6C9-T83GX"

Step 1.3: Set KMS server. could be "kms8.msguides.com" or "kms8.msguide.com" when i used msguide.com it activated but docs say to use the msguides.com
Use the command “slmgr /skms kms8.msguide.com” to connect to my KMS server.
kms7.MSGuides.com
kms8.MSGuides.com
kms9.MSGuides.com


Step 1.4: Activate your Windows.
The last step is to activate your Windows using the command “slmgr /ato”.
If you see the error 0x80070005, it means the server is busy. Please try the command “ato” again until you succeed.



Open CMD.exe as administrator
slmgr.vbs /upk
slmgr.vbs /cpky
slmgr.vbs /ckms
