Microsoft has withdrawn the update it released last week for devices running Window 8 RT.
The Windows 8.1 RT update was released last week, in line with the Windows 8.1 release for standard Windows 8 machines, but the RT version was quickly identified as faulty after a number of users suffered crashes and error messages.
Users reported error messages that told them their computers required repair as the boot configuration data file was missing information. Details surrounding the error have not been released yet, but Microsoft has issued an apology via the Windows store.
A full response and patched update is expected soon.
