However, it seems KB4535996 is inadvertently causing a number of problems on some PCs that install it. As noted by Windows Latest, these range from frame drops when playing games to being greeted with Windows 10’s Blue Screen of Death (BSOD).
Discussing the latest cumulative update on Reddit, one user said: “It’s not extreme, but I say my frame rate in games has gone down 10 frames or so and stuttering occurs once in a while. After uninstalling the cumulative update, everything was fine. Weird.”
A different user, posting on Microsoft’s Community forum, posted: “Newest update KB4535996 is crashing machines. Makes the machines lock up and blue screen at log in screens. Not able to get into any safe mode and uninstall this update. Forcing rebuild and GPO’s to block this particular update. Microsoft says they haven’t heard of any problems. However when you search the web there is a slew of issues just from this optional update.”
