How to fix KB5015885 fails to install on Windows 11?

Issue: Hello, I have been trying to install KB5015885, but it always fails with an error. When I reboot the PC, it attempts to install the update as well but also fails. There is enough space on my hard drive, and I tried restarting the computer several times, and nothing worked. Could you please provide some solutions?

Solved Answer

Since the release of Windows 10, people have gotten used to receiving constant updates correlating with new versions of the operating system. With every iteration, users receive a more secure system packed with new features and improvements – these are usually delivered every second Tuesday of every month.[1]

Unfortunately, not everything always goes as planned, and updates might sometimes even break already existing features or create new issues for others.[2] For some users, the update process might not always go as planned, and Windows updates might simply fail to install, usually with an error code provided.

KB5015885 is one of the latest Windows 11 updates that fail to install for users. Many claimed that the process is initiated but stops at some point (for example, at 25%) and then returns an error – 0x8000ffff, 0x80070246, 0x800f0922, and other codes were reported by those affected.

KB5015885 was released for Windows 11 22H2 versions and is particularly important to certain aspects of the operating system. For example, it is meant to fix issues where users were unable to launch troubleshooters or when V-Sync was causing high latency in games. All that said, these and many other fixes were highly anticipated by users.

5. Disable third-party security software

Once a third-party security software is installed, it changes the operating system in a way where certain processes run through the application, checking their security. There were numerous cases observed when users were unable to update their operating systems due to software such as Malwarebytes or Norton.

Therefore, temporarily disable the operation of the third-party security application and then attempt to download and install the update once again. As soon as the update is installed, you can re-enable your security software.
