Windows 10 - An app default was reset message.

[norman]

An app caused a problem with the default app setting for ..... files, so it was reset to .....

This keeps on popping up, resetting image files, browsers etc to the Microsoft default versions.

This has just started on Windows 10. It does things like change your default browser to Edge. It is really annoying.

This details the problem and gives a solution -

Basically it's caused by Microsoft update KB3135173

A lot of this appears to be due to the Windows 10 Falls Update downloading about 4GB. If you keep getting this try to load and it seems to be an issue then:-

Go into C:\Windows\SoftwareDistribution\ and delete the Download folder.
