Troubleshooting

90% of activation failures come from Defender quarantining the EXE mid-run, a stale KMS cache (slmgr /upk + slmgr /rilc), or picking the wrong product edition. Extract to a Defender exclusion folder (C:\Tools\KMSAuto), run elevated, choose HWID for Windows, Ohook for Office, TSforge for Server.
