I was able to run Hydravision with Crimson on Windows 10 was working to my satisfaction. However with recent upgrade to build 1511 of W10, it was all gradually removed as it regressed to Catalyst now only the video driver 15.300.1025.1001 is installed as confirmed on the device manager. I used system restore, a DDU uninstaller but can't bring it back. It won't even load Crimson. All my applications and utilities are intact. Piriform CCleaner was the first one removed but la test version installed properly. I can't figure it out.
Likewise I was experiencing odd/unusual high cpu/disk activity that was resolve by: Windows 10 Forums thread with notifications, windows spotlight feature and Runtime broker.
