I just finished installing WIN 10 pro on my new i9900k with 64G of memory. These new motherboards for the i9900K series CPUs will only load Win 10 from a fresh install.
I am 3 days into the new OS and have been impressed. I don`t hardly notice anything as far as bloatware. In fact, compared to my other win 10 AMD machine I built 2 years ago, this install was closer to feeling like a win 7 PC. My main screen looks and feels like Win 7. I was like wow!
I recently downloaded the latest (6-18-19) USB boot drive from MS, things went very well. I had to reinstall everything from 8.0 Sonar thru X 1 2 3, and even platinum.
A big thanks to Meng for keeping the older Sonar web site active. Everything I pre owned was still downloadable even using the previous "command center app". I had no problems with serial numbers or activation. I`ve been running Bandlab every day since day 1 and have been doing every update.
For a quick test of the i9900K CPU I loaded 40 tracks of Ozone 8 adv, vocalsynth2, Insight, Nectar, Alloy2, Prochannel Bverb2, Concrete Limiters, Gloss EQs, channel console emulations, Sonitus Delays and 1 instance of Addictive drums2. This pushed the CPU performance meters to 65% across all 16 threads. No overclocking of the CPUs and were running at 3.1Ghz.
This weekend I plan over clocking to 5GHz and running a fresh install of the latest Melodyne Studio 4.2.2.004.
I very much recommend moving into Win 10 with the latest USB boot drive from MS. I think any Win 7 users would be pleased. I was still using Win 7 until last night.
