I suppose we should have a separate thread for this little monster. The first it did was kill VLC. Sound is there but screen is black.
And unfortunately it's unavoidable for some of us even if we have a semi annual deferral set, apparently. https://www.computerworld.com/artic...1803-to-pcs-specifically-set-to-avoid-it.html
Crikey! If they could demonstrate that the pen is fully bug-free and restored to its once glorious glory, then I might be okay with surrendering free will to Microsoft and install their upgrade. ... Who am I kidding? No I wouldn't. -I'd upgrade to a spare, mirrored SSD, then apply everything I've learned since beginning my dodgy tour of Windows10 to attempt a controlled burn lobotomy to sever a useful robot limb from the Redmond Collective. -Unless they've changed the rules a lot, then I suspect I'd be successful. But it's not worth the bother unless this new crop of Cylons can hold a pen straight.
When 1803 came out it slowed down many of the applications I use, especially when terminating. After the most recent update (KB100403) it's fixed and they're back to normal. The most annoying thing with 1803 is that you can't disable Cortana and Web Search without manually editing the registry. Incidentally my device draws a lot more power than before when using the discrete GPU, but that might be because of an Nvidia driver update.
