And multiple reports of problems with Edge (IE replacement) in Win10.
Quelle surprise. Especially as it's built on the IE code.

Having installed W10, my only use of Edge is to open pdfs, but not
through choice. Edge seems to keep resetting itself as default pdf
reader. Similarly, I've been using PSP5 for years, to open any and all
image files, which is fine for all except bmp files, where the MS
program keeps resetting itself as default.

More mildly annoying than life threatening.
