Microsoft pushed another Windows 10 cumulative update (KB4535996) for systems running Windows 10 v1903 and Windows 10 v1909. The update brings numerous quality improvements and bug fixes.
The cumulative update specifically addresses the network printing issues caused by an Internet Explorer security update. In addition, it also fixes the frustrating Windows Search issues for Windows 10 PCs. However, as always KB4535996 turned out to be another troublesome update.
If we look at the user reports posted on the Microsoft Answers forum and Reddit, the troublesome update brings a new series of problems for users. Here’s a list of most frequent issues reported so far:
Windows Search Issues Still Exist
As mentioned earlier, the CU addresses the search issues in Windows 10 OS. But it seems like the update doesn’t completely resolve the Windows Search problem for everyone. A Windows 10 Subreddit confirmed the glitch still exists:
“anyone else still having the problem where some things dont come up in the search unless you type the entire name out? for example : to find notepad if i type “notep” or “notepa” or even just “note” it says that nothing was found, but if i type out notepad it will come up. It started doing this a few weeks ago and rebuilding the index hasnt helped.”
While some people confirmed that the recent CU fixed the problem for them.
Windows Freezing Issue
One Windows 10 user claimed that their Operating System started freezing soon after the installation of this CU. The glitch restricted the system from functioning normally, which could be fixed by uninstalling the update.
Boot & Installation Failure
Another user reported that the cumulative update failed to install even after several attempts. But the OP didn’t mention that if the Servicing stack updates (SSU) were installed before updating the system. Moreover, some users who successfully installed the CU noted that the system failed to boot.
“I just had this update on my PC and now it will not boot. Fails the BIOS POST test with a series of beeps, completely blank screen.”
Screen Flickering Bug
According to another report, KB4535996 seems to be causing screen flickering issues. The problem occurs specifically after signing in.
If you have noticed any of these issues caused by the CU, submit your feedback to Microsoft. There is a possibility that Microsoft may fix some of these issues as a part of Patch Tuesday Updates releasing this month.
