In the changelog, Microsoft explains that the new protections
against a speculative execution side-channel vulnerability
known as L1 Terminal Fault (L1TF) have been applied. The
company says that the vulnerability affects the Intel Core
processors and Intel Xeon processors.
Microsoft has also addressed an issue that causes high CPU
usage and it could result in performance degradation on some
system. The systems with Family 15h and 16h AMD processors were
experiencing slightly degraded performance. The company is also
fixing an issue that prevented apps from receiving mesh updates
As noted above, the update also includes changes
for Internet Explorer and Microsoft Edge. For example,
Internet Explorer and Microsoft Edge now support the
preload=”none” tag. This patch has also addressed
the significantly reduced battery life issue after
upgrading to Windows 10 April 2018 Update (version 1803).
The patch also addresses an issue that prevents some apps from
running on HoloLens. Last but not the least, the update
has also addressed an issue that causes Device Guard to block
some ieframe.dll class IDs.
As you can see, the changelog isn’t really interesting and most
of the fixes are aimed at enterprises and businesses.
It’s worth noting that Microsoft is aware of one known issues
but it has nothing to do with the overall of performance. This
means that the company expects it to install correctly on all
systems. We’re not aware of any failed installs but we’ll
update the article if and when any additional details are
