DuoDriver

Windows Update KB5094126 (June 2026) removed official support for HDR inside remote desktop sessions.

This repository implements a two-driver based patch that brings HDR support back by pinning the HDR source mode in Windows' dxgkrnl.sys driver.

Note: Both "Memory integrity" and "Microsoft Vulnerable Driver Blocklist" under Core isolation must be disabled for the code in this repository to function.

Projects

DuoDriver

A Windows Driver Framework (WDF) kernel driver that provides read-only memory write support for patching protected kernel memory.

It works by mapping the physical address of the target memory via MmMapIoSpace, bypassing page-level read-only protection without requiring a TLB flush.

It also supports traditional MmCopyVirtualMemory based read/write, bulk operations, and kernel module enumeration.

drvcab

A packaging tool that bundles driver binaries into encrypted cabinet files for embedded resource use.

It's used to ship DuoDriver.sys and RTCore64.sys inside the hdrenabler and drvloader executables.

drvloader

A sample program that demonstrates loading unsigned kernel drivers from user mode.

It's internally used for development and testing of the driver components in this repository.

hdrenabler

A user-mode tool that downloads the appropriate dxgkrnl.sys symbol file, resolves the IsHdrSourceModePinned function offset, and patches the kernel to force-enable HDR support in remote sessions.

It can also restore the original behavior.

Supports both interactive and command-line modes (enable, disable, status).
