As of today 7.24.15 is 10240 with the latest upgrade/patches applied does Windows 10 in tablet mode work any better then it did lets say a week ago. I am signed up for the insider program and updated all my desktops and portables to 10240 and all is ok, though when I installed 10240 on my Surface 3 all hell broke loose. Constantly crashing especially in Edge browser, display driver crashes,etc. I only use my Surface 3 in table mode, don't even own the KB. So I just had do downgrade to 8.1 and no issues.
