One time I uninstalled Edge and Cortana from Win10. Some time later Windows Updates started to fail and would rollback. This continued for 6 months and by that time I stopped giving a shit since Win10 is malware anyway.

Another few months went by and I was bored enough to follow the usually useless links to MS knowledge base articles that are given after a failed update.

After another week of trying everything I came across or could think of, I downloaded the install for Edge and reinstalled. Ran the Windows Update again and the god damned thing was successful. Apparently it contained an Edge-specific update but didn’t check if it was installed or not and fail gracefully if it was the latter.
