Also, now all my microsoft apps ask for admin privileges and are from unknown publishers apparently. sfc /scannow doesn't work, error message is something about system update and restarting PC, but this doesn't work. Does nothing. I am on Windows 10 Pro Insider Preview Evaluation copy build 20175.rs_prerelease.200717-1340
The main problem here though is I can't update my laptop. Surface Laptop 3.
