In meanwhile... insiders have to downgrade from build 17070 given via slow ring as many games with security software fail to even start. I sometimes wonder what is MS changing so drastically that security software, which does not care about OS in "Test Mode" with disabled driver signature enforcement, freaks out.

no doubt W10 FCU for me is 2nd best version of Windows 10; but Build 1607 rocks and wins (have only little issues easy to solve them)

I will stay on 1703 untill the next big build. 1709 had some strange FPS issues for me, sometimes would lock at 30 for a few seconds.

FCU? You mean F**ks Computers Up 🙂 Luckily I run LTSB 2016 so that update won't be available until the new build of LTSB which is slated for 2019, so we'll see if they 'force' the new update on you or not then! Also looks like LTSB will be renamed LTSC to fall inline with the Semi Annual Channel rename for Curent Branch and Current Branch for Business.

no doubt W10 FCU for me is 2nd best version of Windows 10; but Build 1607 (AU) rocks and wins (have only little issues easy to solve them)

Same here.

LTSB is also 1607 AU so unless M$ force people onto the 1907 FU version (if that's when it's released) then I'll be staying on 1607 for as long as possible!

I am unable to install the Fall Creator's Update due to a recurring error. I have my Samsung TV hooked via HDMI as a second monitor which works perfectly... no problems. If I update then the TV turns off with a message that there is no signal or signal is incompatible. I have installed all updates available as well as the latest drivers... nothing works. If I roll back to previous version, boom... all working as it was. I would do a clean install but I fear that Windows will update to the latest version, the TV won't work and I won't be able to roll back again. Contacted MS and not a single response. Google search returned nothing too.
