I didn't think it would offer more then the usual Remote connection. In contrast you have Skype to replace WLMessenger offering an improved method for both audio and video with the full features of a chat type engine. TV is an advanced software designed for commercial application mostly while allowing free use by home users. The chat features in that of course would compete with those of other messenger services while companies would tend to expect more out of any remote app for use by their IT and tech dept.s!
I found the QA option was also in the 14379 build as someone mentioned having seen in the previous 372 earlier. At this point if you were compare the TH2 update to the latest you would have a much better total idea of just what the contrasts as far as what is new and changed between the November update and what will be seen in the RS1 at the end of the month.
That is when you will be looking at the full retail RTM for everyone when not only the free upgrade offer is over but a full year of progress for the new Windows has already been seen to for those that now plan to run 10 for the first time. Have a few people at this end that will be.
As for going remote however I would still tend to recommend Team Viewer 11 over the built in option as that hasn't seen much of any change since first introduced in the XP days. It simply gets a new look while still being the same Remote PC option in Windows. TV has been found here to be quite reliable once you have one main if not multiple accounts set up and established as a contact each new pc with the first and others. I worked with on VMs as well as the physical machines for several years now having been able to provide that type of rating.
UPDATE on Findings! With the 14361 build still found on one of the two 10 Pro VMs I still have running one now seeing the 366 replace the 361 as this post is updated the Quick Assist was found in the Windows Accessories on that older build as well being the oldest confirmed and may be found on even one or two more but would have expired by now! The 361 perishes on the 15th of this month as the expiration date.
The second remote pc finishing up the 14385 also arrived without any watermark as well. But even this build will have a limited life span to keep in mind for your primary machine that is.
