Hello Oleg,
Tank you for posting to this community forum.
Based on your description you are looking for a way to enable Track Changes for all users and documents by default.
Because Track Changes is a document property, we can’t enable it by default for the existing documents. If you also want to ensure have it enabled for existing ones, you’d need a macro.
Generally, all such properties could be setup using templates. So, you may create a new empty document, enable Track Changes, and save the result as template.
You may ask the users to set this template as a default, but as these changes would require modifying Normal.dotm file, we would recommend you to follow the suggestions provided by MVPs in this thread: Set custom template as default for all users in Word - Microsoft Community
Best Regards.
Igor
