Microsoft confirms Windows 10 File Association bug, working on a solution

We reported two days ago that Microsoft appears to have messed up a basic Windows feature – the ability to select the default app used to open a document.

According to tests, apps like Photoshop and Notepad++ could not be set as default apps in Windows 10. The new update targets only a few third-party apps as other apps like VLC can be set as default for video files. The issue affects Windows 10 PCs running on April Update, and appeared to be related to a recent Cumulative Update.

Now Microsoft has finally confirmed the issue, adding it as a known issue on KB4462919 (OS Build 17134.345).

There Microsoft writes:

After installing this update, some users cannot set Win32 program defaults for certain app and file type combinations using the Open with…command or Settings Apps Default apps.

In some cases, Microsoft Notepad or other Win32 programs cannot be set as the default.

In some cases, attempting to set application defaults again will succeed.

Microsoft is working on a resolution and estimates a solution will be available in late November 2018.

It appears Microsoft’s advice is to keep trying as “in some cases, attempting to set application defaults again will succeed.

As usual, these bugs in the basic functionality of Windows draws into question whether Microsoft is running through a proper test script before pushing updates out, or are over-relying and then not listening to Insiders.

The advisory can be seen here.
