An user reports that the KB4541335 updated failed to install with error 0x800F0988.

Installation error: 0x800F0988 (KB4551762)
Another user has reported about facing input lag in all games after installing this update. The issue seems gone after the update gets uninstalled.
After this update I have terrible input lag in all games, i7 4771, gtx 1660, 16 gb ram. I deleted this update and marked it as hidden in windows utility, so all is good now. I checked this twice, I don’t know why it’s so problematic for my pc.
Since this is an optional update one can skip it, but these fixes will be part of next Patch Tuesday update, so perhaps Microsoft needs to fix these issues.
