I absolutely hate the constant force update/reboot from Win10 and the huge amount background / network activities/connections.
After most of the win10 background networks connections are blocked and force update/reboot is disabled with Windows firewall, the system are usable now.
I tried and found the new Linux subsystem not useful at all. Real Linux inside virtualbox worked much better for my own use.
Searching the net with firefox/google is much faster than Cortana. I found and installed the 8 year old discontinued "Google Desktop Search" Windows App and it can search files in my location system with 100 times better results and so much faster than latest Cortana/SearchUI.
VSCode is very good.
Visual Studio 2015 is just huge complex monster. Took hours to download and install. I tried download a few popular opensource packages (Python, winscp, ... etc) and used VS2015 community edition to build - all failed to build for one reason or another.
