I'm not a Sonar user, but with regards to Windows 10's apparent slow boot times and sluggishness, I have seen this mentioned around the net at different places numerous times and actually experienced it myself, and that is, after you upgrade, things can indeed seem, and be slower, booting shutting down and general performance, but for whatever reason after some time, reboots etc, it seems to find its feet, and then there is no holding it back, and performance wise and boot and shut down times become very noticeably faster than previous OS's, for me Windows 7 Pro. Seen this mentioned quite a bit, whatever the reason, for me there is no turning back to Windows 7, it would feel like someone has thrown out the anchor, or have their foot on the brakes :)
Going to have a good read of this thread and then see if there is anything in this disabling the onboard sound, HD controller etc for me. Easy stuff to try, and if no dice easy to set it back.
