Here's Zac's video, anyway, from just over a month ago, but nicely concise. Click through to view full-screen, as needed:
The highlights of the 'May 2020 Update' then are:
- Cortana is split off as an application and can be updated in the Store.
- Cortana no longer has access to personal things like your 'Notebook' and home automation - it's re-engineered to hook into productivity applications, such as those in Office/Microsoft 365.
- The Windows Search box now has a 'search with screenshot', to look up whatever's in your selection (text/images, etc)
- Task Manager now knows about, and reports on, SSDs, plus it shows GPU data, including temperature.
- Tweaks to the Windows Ink workspace.
- Option to force people to sign in with Windows Hello (stopping password stealing local attacks).
- More Networking controls in Settings (obviating the need to go into Control panel)
All fairly small improvements, but note that, as always, there's lots of re-engineering going on under the hood. This update is available now on the Release Preview ring, and will start to be offered to the general public in May. As the (ahem) name suggests!
