MICROSOFT HAS told The INQUIRER that it is aware of a bug which has been causing users' default programs to switch to the bundled Microsoft options.
The saga began when a reader told us that, despite being a long time user of Irfanview as his primary photo app, he was greeted with a message saying: 'A default app has been reset,' only to discover that his new photo app was Photos, the bundled offering.
He traced the problem back to KB3135173, a cumulative update issued for February which was pushed out as an update last week. After deleting the update, he discovered the next day that Windows had reinstalled it, and reset the defaults again.
Now a Microsoft spokesman has told INQ, "We are aware of this issue that some customers are experiencing, and are actively working to resolve it." which at least rules out yet another 'we know what's good for you' decision.
Other users have reported similar problems with IE 11 being reset to Edge, and the stock video player being changed back despite the fact that it doesn't support some of the formats for which it is making it the default.
