net stop osppsvc del /f /q “C:\ProgramData\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat” net start osppsvc This wipes the license token file. Office will regenerate a clean (but unactivated) token file on the next launch. The non-genuine message is also triggered by a scheduled task that checks license validity every few hours. To disable it:
cscript ospp.vbs /dstatus You will see output similar to:
cscript ospp.vbs /unpkey:12345 (Replace 12345 with the actual last 5 digits from Step 3.)
