Dear Microsoft,
- I don’t give a rat’s south-40 whether or not an app caused a problem. Handle it with an error message, if you must. Or a recommendation.
- I’ve been to “program defaults” and I have specified what program I want to handle given file types.
- You have NO RIGHT to change those back just because you want me to use your own (often substandard) applications.
- Stop doing this. I configure my computer to my own needs, not yours. This is beyond ignorant, beyond arrogant, beyond anything reasonable or normal. It is stupid and maddening. Just STOP IT.
No love,
The Old Wolf

Had similar problem about a year ago with Windows10, forcing me to update by messing up my computer , and interfering with whatever I was doing . Good thing a blogger taught me how to stop Window 10’s arrogance.
