ks.sys

About this tag
The ks.sys file is a Windows kernel-mode driver associated with the Kernel Streaming (KS) service, which handles audio and video streaming. On WindowsForum.com, users frequently report blue screen of death (BSOD) errors linked to ks.sys, often with bug checks like KERNEL_MODE_EXCEPTION_NOT_HANDLED or DRIVER_IRQL_NOT_LESS_OR_EQUAL. Common triggers include gaming, waking from sleep, adding new hardware such as a SATA DVD burner, or switching TV channels with a tuner card. Microsoft has also patched heap overflow vulnerabilities in the Kernel Streaming WOW Thunk Service Driver (ks.sys) that could allow local privilege escalation to SYSTEM. Troubleshooting typically involves updating drivers, checking for hardware conflicts, or removing recently added devices.
