A report from WindowsUnited lists the known issues described so far. Among the problems facing the Windows 10 April 2018 Update are microphone, sound, and mouse bugs. The most likely scenario for these problems is they are unsupported driver issues. We expect Microsoft will quickly fix these through Patch Tuesday next week. In the meantime, check out the known issues in Windows 10 April 2018 Update.

April 2018 Update Problems
It is worth noting having issues with a new platform is hardly uncommon. Microsoft attempts to create a smooth transition by previewing builds through the Windows Insider Program. Even so, some teething problems are to be expected. That’s why we advise business users to hold off on new Windows builds for a couple of months. With that in mind, Microsoft has recently updated its deferral process for new builds. Through the Windows 10 April 2018 Update, Microsoft has had a few issues. It is believed the company was forced to delay the mooted early-April launch for the update. A blocking bug was said to be the cause of the postponement and Microsoft only just launched the upgrade in April, just missing a May release.
