| Issue | Workaround | |-------|-------------| | Driver signing – Windows 10 enforces EV signing for kernel drivers | Use test mode (bcdedit /set testsigning on) or purchase EV certificate | | Hyper-V conflicts – Nested virtualization may break timing | Disable Hyper-V or use VMware with VT-x/EPT | | Anti-tamper detection – Some software checks for VM or virtual USB | Use hardware-level passthrough (e.g., USB/IP with real dongle) | | Power management – Sleep/hibernate may detach all virtual keys | Set service to restart on resume | | Windows Update – May break driver compatibility | Block driver updates via Group Policy |
