Bug in Windows 10 April 2018 Update prevents setting app defaults for files

Microsoft is working on a fix.

The latest round of cumulative updates shipped to Windows 10 April 2018 Update PCs in October corrected a slew of bugs, but they also caused a curious one of their own. Microsoft has updated its release notes (opens in new tab) for the last two cumulative updates to roll out to the April update, noting a known issue that can prevent "some users" from setting Win32 program defaults for certain file types (via Windows Latest).

From the release notes:

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.

Microsoft says that it is working on a fix that it expects to ship later in November. In the meantime, the only workaround is to keep trying to set app defaults. Apparently, sheer persistence occasionally will allow setting a default to succeed.

  • Is anybody else having a mindbuggingly slow right-click new context menu?
  • I thought I was the only one with this problem, good to know I'm not.
  • I haven't decided yet if I'm happy 😊 about the fact that I'm not alone then.
  • Aha! This has been happening to me with Adobe Illustrator and Photoshop CC. Glad to know it's a bug to be fixed.
  • I guess we will see a cumulative update on November 13th addressing all the cumulative flaws including the October 2018 Update on file bugs...
  • Not the official release version of 1809? I've waited too long!!!!!!!
  • Microsoft seriously need to rehire programmatic testers and a proper quality assurance team. This is becoming ridiculous and mind numbingly exhausting especially with W10 Home as you have hardly any control over updates. Microsoft need to allow us, users to select which updates to install or not because it's more than apparent with this "cost saving mentality" we are going to see a whole lot of preventable issues with Windows updates..
  • Make sure that your sound card is working properly and is running with updated drivers. To fix audio issues in Windows 10, just open the Start and enter Device Manager. Open it and from a list of devices, find your sound card, open it and click on the Driver tab. Now, select the Update Driver option.
