Windows 10 users face numerous issues installing the latest KB4579311 cumulative update, and for those who can install, they are reporting various bugs, including performance issues.
Microsoft released the Windows 10 KB4579311 cumulative update on October 13th, 2020, and since then, users have been reporting problems getting the update to install, crashes, performance issues, and boot problems.
Due to the varied hardware and drivers running Windows 10, there will always be issues when a new cumulative update is released, but there appears to be an uptick in reports with this particular update.
The most common issue users are running into with Windows 10 KB4579311 is the inability to install the update in the first place.
"Hi, I've been having an issue with Windows Update KB4579311. When it gets installed it causes the Explorer to crash repeatedly until it eventually logs me in, at which point I can use it as normal. BUT, the crashing increases time it takes to log in and load everything up. It's very annoying," one user reported.
