KB5025239 is a cumulative update released on Patch Tuesday of April 2023. It targets PCs running Windows 11 22H2. It fixes a total of 59 vulnerabilities, five of which are announced as critical. This is a mandatory security patch. Clearly the Windows Update service ensures, automatically, downloading and installing it.
Unfortunately, not everything seems perfect. Several reports mention malfunctions. Returns evoke crashes of the file explorer, the disappearance of icons on the desktop or even performance problems.
The good news is that all of these worries don’t seem too widespread. However, they are quite different in nature. For some the situation is critical with serious performance issues. The startup times of applications, software, games or even the PC are longer and SSD performance is down sharply. These symptoms are seen after installing KB5025239 but also KB5025224 targeting Windows 11 21H2.
In other cases we have a misleading report that TPM 2.0 is not installed and the device is vulnerable due to disabled LSA protection when enabled (this bug has been known for several weeks now). There are also unresponsive icons that disappear and then reappear after installing the update. Windows Update service crashes and issues appear with File Explorer, Taskbar and Task Manager.
How do I fix KB5025239 issues?
It is currently difficult to quantify the number of victims. On the other hand, reports are increasing as the deployment of KB5025239 intensifies.
It is possible to correct all these problems. Just uninstall the update.
To do this, go to Windows Update then ” update history then click on “uninstall updates”. All that remains is to select KB5025239 from the list and validate by clicking on “Uninstall”. A restart of the PC is required for the changes to take effect.
All this once again highlights the delicate Windows maintenance operation. Windows 11 is an operating system. It is vital and critical so that a malfunction can have catastrophic consequences (loss of data, production stoppage, loss of money, etc.).
