The script uses the built-in Windows Software Licensing Management Tool (slmgr). The command usually looks like this:

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

(Note: W269N... is the generic key for Windows 10 Pro).

The script immediately checks if it is running as Administrator. Without elevation, the activation fails.

@echo off
net session >nul 2>&1
if %errorLevel% neq 0 (
    echo Requesting administrative privileges...
    powershell start -verb runas '%0'
    exit /b
)

Open Settings → Update & Security → Activation → "Troubleshoot" → "I changed hardware on this device recently"

Let us look at what an actual CMD script from these repositories looks like. (Note: This is a structural analysis, not a copy-paste instruction).

It is vital to distinguish between activation and licensing. Using scripts found on GitHub to activate Windows via public KMS servers creates a valid activation ticket on the machine, but it does not equate to owning a legitimate license from Microsoft.

After activation, the script re-enables Windows Defender and deletes temporary files.

Microsoft allows Windows 7/8 users to upgrade to Windows 10 for free. The HWID method tricks the Microsoft activation servers into thinking you performed a legitimate upgrade. Once activated, the license is permanently tied to your motherboard.
