It works. Bug: lockscreen background picture doesn’t show up when letting the tablet sleep for more than around 10 minutes.
Despite the promises no improvements in performance though, Edge browser still loads heavy pages dead slow, some sites take almost 10 seconds to appear. It is even a bit worse than before update. Ok it has extensions and adblocker now, but there was a system wide adblocker available before which could achieve the same. So Chrome destroys Edge in this respect. However Chrome has worse scrolling performance and kills battery faster. Only interesting feature is the Ubuntu subsystem, but 99% of people don’t need that.
So it works, but I wouldn’t bother updating if you don’t need the linux stuff, I think updates won’t make windows better on this tablet. Waste of space and time in my opinion. I use Android most of the time, which is much better optimized for this hardware.
