So...before I knew there were any problems with Windows 10/Microsoft Office compatibility ...I updated to Windows 10 on my secondary almost brand new computer (did this last week). The computer was on Windows 8.1 (a nightmare operating system) and is primarily
used for web browsing so had nothing much on it thankfully. After the install, I found that ALL my Microsoft Office programs had disappeared. Vanished. The icons were on the desktop, but they were blank. I could not find the programs on my hard drive anymore
(despite having Office 365 previously installed).
I then found lots of forums like this one where others have been having precisely this same issue for many months now (and other worse issues as well, such as not being able to open or save their existing documents).
Having spent the whole weekend trying all the suggested fixes, and with nothing working, I reinstalled Office 365 and now I have the icons and their associated programs back.
I am totally shocked that such a big corporation as Microsoft could launch Windows 10 and encourage mass transition by millions of users when something like this seems to commonly happen to those who install Windows 10.
What I don't get is why it only happens with SOME downloads/SOME computers, but not with EVERY computer. If it happened with everyone, there would be massive media interest and even more complaints of course. The fact that it is happening to many thousands
of people is not as significant as if it happened to hundreds of thousands.
The whole process has been disturbing and I am buying a MAC as I can't stand the glitches with Windows anymore. I also read that their in-built anti-virus software Windows Defender rated 0.5 out of 6 recently for picking up viruses and malware.
