In this build MS has added plenty of new options to the Settings app, including new taskbar options, a new Battery usage history page, webcam options, and even a few options related to Sets. All of them are hidden and not visible by default. Spoiler
But they also said they might have something later this week for RS_PRERELEASE. Yeah they pushed out a build earlier this week for FE_Release.
I don't think so, because these options were not present when SETS feature was working on Insider Preview few years ago.
I found out what caused my computer to boot and reboot slowly it was the Samsung NVMe driver. Has anyone noticed that in this version of Windows it is not possible to set the affinity for any application? or it is only me?
