So I have various issues with my surface since the latest big update... What I'm wondering is if a full reset/fresh installation of windows would help with any of these? In my mind installing update over update over update will eventually cause errors (I have the SP4 since 1 1/2 years) and a fresh install would help? I don't know My issues are things like this: - Since 1709 I had ~3 full freezes where I had to hard-reset the tablet, no bluescreen just not reacting to anything anymore (cannot recall that ever happened before) - Touch input, especially with the on screen keyboard is laggy/slow - Multi touch / Pen input sometimes just doesn't work! Only restart resolves issue... - I have the most recent update KB4054517 installed and also the driver updates from a few days ago. I also ran sfc /scannow which didn't find any issues. Any ideas? While I'm at it: MS, can you please, for the love of God, make a Brightness slider in quick settings? How hard can that be!?
