Error in opening machine

Post by user03 »

Recently upgraded to Windows 10 version 1803 (OS Build 17134.48). Pre-upgradation the machine worked perfectly fine.
Post upgradation I get this error

Failed to open a session for the virtual machine IE11 - Win7.

Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}


Have ensured that Hyper-V is disabled and that virtualisation is enabled in BIOS.

Would appreciate if anyone can suggest a solution.
Regards
