Topic: Double drivers in Programs & Features (Win 10)

Hey, small little probably insignificant issue (but I'm trying to lower my dpc latency via latencymon so am going through every little geeky thing to optimize my system completely)

As you see, I (accidentally) installed two RME drivers for my RayDat, one newer than the other, but both seem to be installed, and when I try to uninstall the olders version I get this image:

Unrelated to that issue I assume, I get this info in LatencyMon (this is on a clean reboot):

Highest ISR routine execution time (µs):              17.669913
Driver with highest ISR routine execution time:       Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%):          0.055393
Driver with highest ISR total time:                   portcls.sys - Port Class (Class Driver for Port/Miniport Devices), Microsoft Corporation

Re: Double drivers in Programs & Features (Win 10)

You can have 10 entries there - doesn't matter. The installed driver is listed in the Device Manager under RayDAT, and only that one is active.
