I'm amazed how Microsoft could go from an os that did everything you need (xp) to a bloated but somewhat improved os (7) to a barely useable unfinished os (8) and then get accolades for releasing something barely better (10).
My latest run-in with 10 is with the built-in "photos" app. I installed irfanview which is much more powerful, and windows immediately proceed to reassociate all image formats with the built-in viewer. At least I got a notification. But it included no way to undo Microsoft's "fix", which kept on being applied every time I told infanview to take over jpgs again.
The solution seems to be to uninstall "photos". Well easier said than done. "Add/remove" programs does list "photos". But it helpfully indicates that uninstall is not a supported option but flashing when you click that button.
The solution was to Google. Thank goodness for Google in this messed up world of windows 10. Because to un-install photos you need a rather long powershell command: Get-AppxPackage *photo* | Remove-AppxPackage Luckily Google knows your pain and it's the first hit.
Now recall xp, fondly, where you never had to Google to know how to remove an app. Or 7, where the built in search was good enough to find the right screen to do it.
2 years till Microsoft stops supporting 7. Oh what am I to do.
