Microsoft’s Windows 10 April 2018 Update has been available for manual download since Monday (April 30). While most users will wait until the automatic updates start next week, those who have downloaded the upgrade are reporting problems. Indeed, the more people downloading, the more bugs there are.

Over on the Microsoft’s Community Forums, users are reporting a bug that’s causing low disk space warnings to be displayed. It seems the warnings are caused by inaccurate driver letters in recovery drivers.

Users on Microsoft’s community says Windows 10 April 2018 Update is notifying on a separate partition. This is 449 MB and is not visible in the update notes. The recovery partition seems to have not been meant for the release, but is included in File Explorer.

Opening the drive does nothing, just taking users to an empty folder. While we expect Microsoft to fix this problem through Patch Tuesday next week, you can stop the notifications manually.

To do so, use DiskPart to remove the assigned driver letter and hide the file. While this will not remove the partition, it will stop the notification warnings of low disk space. To use DiskPart, head to Command Prompt and type diskpart in the command line.


Now run these commands individually:

  • List volume
  • Select volume 3
  • Remove letter =”E”

Other Bugs

As we reported earlier, Windows 10 April 2018 Update has plenty of new bugs. 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.
