Windows 10 – Older Software Won’t Install from Disc Anymore

Reason: The Win upd disables a driver called secdrv.

You can manually invert the process by doing the following:

Go to Start, enter cmd (with admin rights), enter the following:

1) “Arm” and “activate” secdrv at once by entering sc config secdrv start=auto . The driver will then be automatically started at startup which MS does not advice.

2) “Arm” the driver by entering sc config secdrv start= demand . This will load it when needed. To load it directly enter sc start secdrv . If the upcoming log contains the line “4 RUNNING” you can go on.

Deactivate the driver with sc stop secdrv (single time) or sc config secdrv start= disabled(by default) if needed.
