If people can run legacy Windows apps without Windows, they will gladly move to a new platform simply to be free of Antimalware Service Executable and the constant useless updates.
And that is, at best, a move from the fire into the frying pan. You'll get cooked more slowly, but you'll still be "done" by the end of the process.
Trading Microsoft for Google is merely a lateral move. Your privacy is still being raped, your control can be taken away in a heartbeat, if your data connection goes down you're mostly dead in the water, and the "deal" can be altered at any time.
The problems with fighting an addiction by substituting what is currently a kinder-but-gentler drug are well known. The "replacement" can easily become as harmful as the original drug, and sometimes you end up addicted to both. Painful though it is, the best course is to go cold-turkey. In this case that means moving to Linux, adopting LibreOffice or something similar as an office suite, and finding FOSS alternatives to the rest of the software you use.
In the beginning it may be necessary to run Windows in a VM for some applications, but the ultimate goal needs to be a complete rejections of Microsoft, Apple, and Google. These companies are not your friends; remember, they are PUSHERS and will always try to seek more and more control over your computing power, your data, your privacy, and your bank account.
Stop feeding that ugly beast that wants to own your entire existence!
