As with every new build in the Dev channel, this update also has a few issues that Microsoft is aware of. Here is a list of those known problems:
- A problem with the secondary drive (Non-OS drive) being inaccessible after installing a game from the Microsoft store has been reported since the release of build 20236. Microsoft has proposed a workaround: You must change the location of the default storage before installing it. This can be done through:
Settings -> Storage -> Change where new content is saved.
- The update process hangs for long periods when downloading the new builds.
- Live previews for pinned sites in the Taskbar have not yet been published for all insiders. Hence, users might see a blank or grey image when they hover their mouse over the Taskbar’s thumbnails.
- Some Windows Insiders may experience Windows PowerShell crashing on devices with ARM architecture. Microsoft has provided a workaround for users to run the 32-Bit version of PowerShell or download the modern PowerShell 7 from Microsoft store and use it.
- Some users see the error 0x80070426 when signing into certain apps using their Microsoft accounts. Microsoft claims that rebooting the computer resolves the problem.
- Some insiders are claiming that no drives appeared Settings -> System -> Storage -> Manage Disks and Volumes after installing the build 20251. Microsoft has asked users to manage their drives through its legacy Disk Management tool for the time being. You can also open legacy Disk Management by going to Run –> diskmgmt.msc.
