Seams it's not possible to turn off Let apps run in the background in Setting>Privacy>Background apps? If I turn it off and close and reopen Setting, I see it turned on. Bug, or intentionally? Let's see.
It have nothing to do with the Task Scheduler entries and/or startup items. That setting is for UWP apps like Mail/Cortana/Skype/etc. Not for regular desktop programs. BTW I noticed this also in Build 17101.
Guys. Take the decision to install this build on my desktop. After the first reboot, it remains in the windows logo. I have to reset and I get a failure in the installation 0xc1900101. In my old laptop core2duo work perfect. Desktop. X99 ultra gaming, i7 6850k, 32 gigs ram, gtx 1080. Please any advice.
