You might recall that older versions of Windows 10 recently got some cumulative updates with performance fixes (among other things), and now it’s the turn of the latest incarnation – the April 2018 Update – of the desktop OS to get a pile of patches sorting various issues.

This is a batch of troubleshooting bits and pieces (as opposed to security updates), and amongst the problems solved are an issue that meant the most recent versions of Google’s Chrome browser stopped working on some devices, and a bugbear that caused the HDR streaming calibration slider in Video Settings to stop functioning.
