Some Windows 10 users reported that Microsoft’s optional update, released in the last week of February, had problems. Optional update KB4535996 was released on February 27 to fix Windows Search and print failures. However, some users have made a serious error after upgrading the optional update.
On February 27, the software giant released an optional KB4535996 patch through Windows Update, along with an offline installer. After the installation is completed on the basis of Windows 10 1909 / 1903, the system compilation version number will rise to Build 18363.693 / 18362.693.
However, based on user forums, Microsoft support community and user feedback on social networking sites, the optional update has a number of serious issues, including inability to install properly, regular blue screen displays, and performance issues after the upgrade. First somepeople say that KB4535996 cannot be installed and display generic error messages such as 0x800f0922 and 0x80070003.

Windows Update lists this as an optional update, and I can click Download and Install. It downloads 0 to 100%, then it takes some time for the installation to reach 100%, then asks for a restart, then starts updating on the blue screen: count to 6%, and then restart. Indicates that the update could not be completed, that the changes could not be undone, and that the troubleshooter could not find any reason.
The second is that the user indicated that there was a “random card-dead” option after the update upgrade and other performance issues. One user said:
With the latest driver, xpS 15 installs KB4535996 after a random card death problem.
Another user indicated that
I just installed this update on my PC and can’t start it right now. A series of beeps (a completely blank screen) caused the BIOS POST test to fail.
If you experience these issues as well as during the installation of the optional update, you can choose to uninstall the update:
1. Open the Settings app by Windows and I
2. Click the Update and Security option.
3. Jump to the Update and Security screen.
4. Switch to the Windows Update tab.
5. Click the “View update history” option.
6. Click on the “Uninstall Update” link.
7. Select the update and uninstall it.
