I got my FlashAir a few days ago and I installed in my 3 laptops. After only a few days of use came the W10 build 1607 update. I updated my laptops and my FlashAir was really flying. I needed to install again the FlasAir ( this time only in one of the laptops). It is working good after re installation.
I have discovered some troubles with this update. W10 build 1607:
-My SD card readers stop working in 2 out of 3 laptops. Needed to find out the original drivers and re install again.
-In my wife laptop the Microsoft Solitaire suite didn't work at all, needed to un install and re install again.
Still have not tested for all hidden problems with this update. Be aware that if you updated , maybe some systems or software won't work.
Hope that this post will help somebody.
