Microsoft reinstituted the Windows RT 8.1 update it pulled from its Windows Store after some Surface RT owners reported their tablets suffered from the Blue Screen of Death.
In a message posted to a support forum, Microsoft said, “The update to Windows RT 8.1 is once again available as a free download in the Windows Store for users with Windows RT devices.
“We immediately suspended availability of the update after reports that a very small number of Surface RT customers — around 1 out of every 1,000 Surface RT 8.1 installs — had experienced an issue that left the update incomplete and their devices unbootable.
“This was due to a rare situation where firmware updates had not completed at the time of the update to RT 8.1. In most cases, if a customer encountered this issue the result was simply an extra reboot. However, for a very small percentage, the boot configuration data was affected which prevented a successful boot.
“We worked to quickly resolve the issue and now encourage customers to update their Surface RT devices. Surface Pro and 8.1 customers were not impacted by this issue.”
According to initial online reports, some users had wrapped up the Windows RT update only to see the “Blue Screen of Death” (BSOD) display and an error message stating, “Your PC needs to be repaired. The Boot Configuration Data file is missing some required information.”
By corrupting the boot configuration data, the update rendered it inoperable.
Microsoft Surface RT tablet debuted a year ago, has been the only Windows RT-powered device that has sold in any meaningful quantity.
