I have on my Pc Microsoft Office 2016,I also have the disc.I have been using it for 2 years. Recently due to bad crashes/seizing etc I was forced to do a totally clean reinstall. Now Microsoft are sending me messages to inform my copy of office will close in 4 days. After all these years I have no idea of activation code, apparently there is some way of finding it, but I'm not too well and anyway I have the disc(also reinstalled after factory reset) so why the bother.is there anything I can do to prevent the system doing me a great wrong?
