Windows 11 KB5025305 bugs: Installation, gaming issues and Kaspersky warning

The latest optional Windows 11 update – KB5025305 – is causing many issues for some users, including those with the Kaspersky antivirus solution installed.

Windows 11 KB5025305 was released in the last week of April 2023 with some nifty improvements, including new animations for the Widgets taskbar button. You’ll notice these new animations when a new announcement appears on the Widgets taskbar button. Or when you hover over or click the Widgets taskbar button.

Another significant change is a new toggle control that lets you get new features and updates before others. This switch turns on “Configuration updates” for Windows 11, prioritising your device to get the latest non-security fixes and improvements, such as a search bar in Task Manager.

The update completes successfully after going through 0-30% and then 31-100%.

Another user reported that the update consistently stops at 25%. When they restart their computer, the update remains at 25% and does not progress further.

One user experienced game freezes after installing the update. They noticed the issue when playing Metro, as the game worked fine the night before the update. The problem occurred after installing the KB5025305 update.

Some users also reported that Kaspersky antivirus displayed a message warning of potential future limitations when running on the updated version of Windows 11. As shown in the above screenshot, the warning says, “There may be some future limitations when running on this version of Microsoft Windows 11”.

Another user claimed that the update may have caused a problem with the firewall, suggesting that Kaspersky needs to release an urgent update to correct the conflict. The issue is believed to have affected thousands of computers worldwide.
