Dear Thirumalai94,
That's exactly what happened to me here in Brazil. I signed up on the 19th, and so far this morning, no button has appeared in my MS Word, PowerPoint, etc.
I had purposely canceled Windows 10 updates using the stopupdates program. I released the updates, did everything possible, and nothing.
This morning, I logged into MS Word and went to File > Account > Update Options > Update Now (check for and install updates).
I said "Update now", and there was an update available. The service updated, restarted the MS Word app, and when it came back,
the "Copilot" button appeared in the "Home" tab to the right of the Microsoft Editor button.
Hope it works, Thirumalai94.
Attention: I wrote in English, but translated directly from the terms and words in the MS Word app in Portuguese. Perhaps the original English names are not exactly the same as those I typed here. I suggest attention.
