I was surprised
The April June update worked fine for me, it took about an hour to update after download.
Everything seems to work as I would expect so far, even Chrome which I use with LAN access for the development tools. No SMB1 use and wtf is media center content? Am I a poor web dev for trying to be as cross platform as possible and never using smb1 or not knowing how to integrate media center content with chrome?
The update did reset some of my privacy settings and deleted my firewall program (Private Firewall 7) due to "not compatible" or some such twaddle. I kind of expected this, yet I was surprised to find that my start menu was not altered.
I had to uninstall private firewall properly (the update didn't... it left most of the files and just deleted and disabled the loading of the NDIS driver) before I could install the very same version again despite the incompatibility".
I can only presume Microsoft does not like user installed tools that interfere with their data collection activities.
I have so little respect for Microsoft that I would have had a good time bitching about how bad the update was and how it fsckd up my machine. But alas, other than just deleting code it did not like and giving applications access to things I had previously blocked (camera, microphone, contacts etc. etc the update was flawless.
I am not sure if I am being sarcastic. Usually there are so many work continuity breaking issues that a few less major issues are acceptable. I have obviously been conditioned by Microsoft into accepting a few niggles with a sigh of relief.
YMMV
I reboot into Win 10 now and see if anything has changed
