Microsoft warned end users that performing Windows XP SP3 and Windows Vista SP1 upgrades from copies of XP SP2 and Vista RTM, respectively, that have Onekey Recovery 5.0 installed will cause the operating systems to display a black screen following reboot. According to the Redmond company, the issue is generated by an incompatibility between the two service pack releases and Saming OneKey recovery software driver Safnt.sys.

This means that deploying SP1 on top of Vista RTM, or SP3 on top of XP SP2, with Onekey Recovery 5.0 also installed, will result in a black screen of death. Microsoft revealed that this scenario would happen whether the service pack upgrade is performed from Windows Update or through any other method. “This issue occurs when the computer contains Onekey recovery software that is earlier than version 5.1. If the computer uses the Onekey recovery software version 5.1 or later versions, this issue does not occur,” the company revealed, explaining that “Windows Vista SP1 and Windows XP SP2 are incompatible with Onekey Recovery 5.0.”
