Towards the end of July, Microsoft released KB5028244, its C-release non-security update for the month. The update was one which brought in multiple issues like those related to UWP and Win32, BitLocker, printers, and more. Find the full release notes of the update in its dedicated post.
However, the update wasn"t flawless as Microsoft confirmed a major bug that was causing video codec issues, and Windows 11 was affected too. Today, the tech giant has confirmed another bug in the update. Microsoft says that applications installed via ClickOnce are incorrectly showing as not installed. Microsoft has issued a known issue rollback for this bug.
On its health dashboard, Microsoft explains the bug in detail as well as its workaround:
After installing KB5028244 or later updates, apps which were deployed using ClickOnce might begin to prompt for installation even when the ClickOnce apps are already installed and marked as “trusted”.
Workaround: To temporarily workaround the issue, uninstall the impacted ClickOnce Application and reinstall the application again.
