Here is how you can fix the new Windows 10 Cumulative update KB4565503 causing Installation failure
It seems to be a difficult time for the Windows 10 users after the release of Windows 10 May 2020 aka 2004 update. Microsoft recently released the Patch Tuesday update KB4565503 for Windows 10 Version 2004 aka May 2020 update. It also released the Patch Tuesday update KB4565483 (Builds 18363.959/18362.95900) for Windows 10 version 1909/1903.
With KB4565503, Microsoft said that the company has fixed the problem that was causing lsass.exe to fail and generate a c0000008 error. The update also improves operating system security and the security of the Microsoft Store. Other fixes include addressing graphic glitches in windowed games, and problems printing large files.
But as spotted by TechDows the recently released Patch Tuesday Update KB4565503 for Windows 10 May 2020 Update version 2014 is repeatedly failing to install for some users. The update that these users are getting is KB4565503, and the easiest way to tell if it’s already installed is to click the Start menu and type winver. If the OS build number is 19041.388, then the update is already there on your device.
However, the company said on the official KB page of this update, Microsoft says it’s aware of just one issue with KB4565503. “When using some apps, such as Microsoft Excel, users of the Microsoft Input Method Editor (IME) for Chinese and Japanese might receive an error, or the app might stop responding or close when attempting to drag using the mouse,” the company explains.
How to fix KB4565503 causing Installation failure?
Well, according to the Microsoft engineer that replied on the forum when the users started reporting the issues. There are two workarounds that can fix this update issue. The first thing you should try is manually downloading the cumulative update and installing it on your device.
If you are using Windows 10 from the last two years then you must know this is something that has helped in the past as well when other cumulative updates failed to install, and it mostly indicates that the problem resides in the way Windows Update unpacks the update and launches the installation process.
Another thing that you can do is reinstalling Windows 10 in repair mode. It could help on devices that are locked in an infinite installation boot, even if the update fails to install and you manage to get back to the desktop, Windows Update then downloads it once again and offers to relaunch the installation process, only to fail once again and thus repeat the whole thing.
It is yet unclear that when will be this issue solved as the company has launched the Cumulative updates last week and as according to the past the company has fixed this type of error and issues in a monthly update.
