Your office is not genuine

[zabovs]

I've started getting Office is not genuine banner. Was using version 41 manual activation. Tried this v44 same stuff. Not sure what am I doing wrong here, Same windows, same office, haven't even updated it. It is still activated though.
Version 2206 Build 16.0.15330.20260

I switched to https://github.com/abbodi1406/KMS_VL_ALL_AIO instead and re-ran the activation. The banner is gone now.

Works for me on Office LTSC Pro Plus 2021 @ Windows 11 Just put this all cmds to cmd terminal and wait for Office activation window (basewin.pl source):
ATTENSION, when delete commands getting error just delete this entries in regedit manually
reg add HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration /v CDNBaseUrl /t REG_SZ /d "http://officecdn.microsoft.com/pr/55336B82-A18D-4DD6-B5F6-9E5095C314A6" /f

Can confirm same issue here, it used to work but now it's saying

Office Version: 18.2210.1203.0
Windows 11 Pro
Version: 21H2

Remember that this little tutorial only works if you have activated office before. I can't help you more, unfortunately I don't know what happened in your case. 😅

I'm guessing microsoft pushed an update that detects the patch for office. I have activated office before and it worked fine.

Just got the same warning after getting the 2302 update.
