Hey man! How Are You???? Well, I think I was one of those responsible for this situation, at least, different. I noticed several errors in Build 17.133.73 that could not be in the Release preview. I recommended that you do not release this build due to compromising performance errors. I've Working hard for almost three days, performing tests anyway. I think they got the message. I'm glad we will have an impressive RS4, soon !!!!!!!!!! (Forgive me for my bad English)
I have Updated all my Machines and i think i know why they did it this way , for me i cant install any updates on 17133 the update Process stops after restart in an endless Looping circle. And they needed to Fix the Windows update platform and maybe a new build is the only way.
