I have been very happy with the Windows 10 builds. Most of them have at least been “no visible change” for me. Build 10547 however, was not like that.
I had heard of some issues with that build from one of my co-workers, but nothing specific enough to not make think it was other than an anomaly. However, when I installed the build, I was very unhappy.
First, I rarely shut my machine down. I had to do a hard shutdown 3 times on my machine after installing Build 10547, because the screen was black and only the mouse pointer was visible. After I was able to get into the machine, the network adapter wasn’t working. It has worked fine for Windows 7, 8, 8.1 and every other build of Windows 10. I kept getting activation errors for Office programs. after 2 hours, I finally had to revert to the previous build.
Build 10550 is supposed to have addressed some of these issues. Cross your fingers.
