Windows 10 KB4592438: Watch out for these issues in the latest update

Windows 10 KB4592438 issues

With Windows 10 KB4592438 cumulative update, Microsoft has
delivered a fix for a highly frustrating ‘Blue Screen of Death’
bug that has been crashing PCs with Intel NVMe SSDs drives
since May. Unfortunately, the update comes with multiple
issues, according to user reports on the forums.

Like the
November 2020 updates, Windows 10 KB4592438 for version
2004 and version 20H2 also appears to be problematic in terms
of installation for some users. In addition to the installation
problem, users are reporting a couple of other bugs as well
including an issue where spikes in CPU and memory usage are
observed.

Note that users have also encountered these issues when
applying Windows 10 KB4592449 for version 1909 and 1903.

KB4592438 fails to install

The primary issue again appears to be an installation problem
where Windows 10 will try to download the update in the loop
and the process will fail with generic error messages, such as
0x8007000d, 0x800f0922, etc.

For example, one error message states that “some update files
are missing or have problems. We’ll try to download the update
again later. Error code: (0x8007000d)”.

If you are one of those affected by the installation failure
problem, your best bet may simply be to use the Media Creation
Tool for an in-place upgrade. Or you can also pause the update
temporarily.

Performance issues

On Reddit
and Microsoft
answers forum, users are reporting that
Windows 10 December 2020 cumulative update is causing lags
when opening and closing programs.

Others have also noted that the update has caused a massive
spike in resources usage (CPU and RAM).

“I am getting some weird spiking CPU usage after my update.
Like shooting up to 100% up and down with just a browser open,”
a user noted in a post on Reddit.

“Certain windows applications such as Task Manager, Disk
Management and Windows Defender Firewall with Advanced Security
lag severely when the window is moved by dragging it around the
screen. CPU usage goes up to around 25-30% on one core,”
another user highlighted the same problem in the Feedback Hub.

There are a couple of other bugs which have been reported,
including Blue Screen of Death errors. Likewise, some AMD users
have reported that they’re getting ‘Application error’ when
launching programs like Command Prompt.

Some users have also reached out to us with complaints of Blue
Screen error, Bluetooth and other problems after December
patches.

If you are one of those hit by the latest Windows 10 update
failure, there’s no known solution or workaround, but you can
always uninstall the update and hit on the pause button.
