I just installed this cumulative update MS released yesterday to my main HP Cubase 8.5.20 production and loaded a semi-large project with quite a few plugins, Halion 5, SSDrums, Neo Soul EP etc and all seems fine. Also, to my portable Lenovo Thinkpad Workstation. All fine.
FYI: People (some)on the Release Preview are having problems with installing this update in that it installs to 99% and then reverts back to the previous build because it is unable to complete the update. I have this issue with a consumption device (Surface 3) that I run W10 Release Preview on. MS aware and working on it so they’ve said.
I’ve installed the latest update on five NON-INSIDER machines so far and none of them have had a problem…not that you won’t!
