We've tried to use MediaWiki and other fancy solutions (inc. O365's SharePoint/online OneNote) and desktop OneNote is the only one that stuck. We have .one files for each major topic with sections and pages within them. It is kind of a "low tech" solution, and maybe that is why it works. It gets out of the way, easy to backup, no downtime, etc.
Although Microsoft keeps threatening to discontinue the desktop version of OneNote.
We use OneNote at work. I don't really like it as a Wiki tool. Its a superfast solution to get the work done, but the search sucks. Its difficult to get it organized if there is a lot of documentation. Its amazing to use as a personal notebook but not wiki.
