Windows Updates have a dreadful track record of late, with
almost every single update causing users some serious problems.
There are multiple reports on Microsoft’s forums, our comment
section, and Feedback Hub from people complaining about a range
of issues after applying Windows 10 KB4541335.
Windows 10 KB4541335 is an optional update that you might want
to skip for now. Over the weekend, many users have documented
problems with this patch. Some have said that the update broke
their computer, others are seeing Blue Screen of Death (BSOD)
and many experiencing performance issues.
Other users are having even bigger problems. One person said
their computer doesn’t work after the update.
“My machine bricked all night and I had to unplug and roll
back. Finally, after about 30 minutes it uninstalled and I
could go to Settings and pause updates for a month. This is
happening way too often,” one user wrote.
“This KB Update also slowed my PC,” another user said. As per
one user, the update also causes Ethernet problems and some
apps are failing to access the internet.
“Just after rebooting the desktop and check the Task Manager
and found that the CPU above 50%, Memory 95% & HDD 100%
utilizing,” another Windows 10 customer documented the problem.
Another user also told us that the KB4541335 update crashes the
system and later causes 100% disk/CPU usage. “[My PC] has
become highly unstable after the update,” one of the affected
customers told us.

number of reports has increased significantly over the past few

safely skip it, at least for now.

tab on the left side.

update will be removed. If your PC is still bugging out after
uninstalling the patch, then your best bet is to reset the
device from Settings > Update & Security > Recovery.
