Windows 19 is here. No hang on, that's confusing - it's actually 2004. Any clearer?...
Actually as of May 28th 2020 Windows 10 has had it's first upgrade of the year, calling it version 2004.
So that makes it version 19 if you have read my previous on the number of upgrades since Windows 10's release in 2015. I guess it doesn't really matter to most what its called - after it's still Windows 10!
However.....BEST ADVICE is to not go hunting for it - just let Windows do its thing and it should install itself automatically in good time (if it doesn't then you may have other problems). There are few changes in this release - but nothing worth the risk of forcing an upgrade if it could problems - best let any issues get ironed out first.
