Windows 10 update bugs: BSOD, sound, slow boot, and WiFi

Updating your devices to the latest version of Windows 10 only
to discover that your sound and WiFi has stopped working is
nothing short of a nightmare. Unfortunately, Windows 10’s
monthly updates have been consistently running into such
problems and
Microsoft’s operating system hasn’t been in a positive light
lately.

Windows 10 KB4532695 is the latest update that many users
installed in a bid to fix File Explorer’s broken search bar,
but it reportedly includes a whole raft of other flaws.

The problematic update, which was released in late January, is
now breaking down even more PCs and causing performance issues.

KB4532695 causes BSOD, boot failure and system slowdown

Initially, it appeared that Blue Screen of Death (BSOD) is only
hitting a small set of computers, but the problem appears to be
widespread now.

Several users in our comment section and Microsoft’s forum
are pointing the blame at KB4532695 for a Blue Screen of Death
(complete crash of the PC) with a critical error message and
different stop codes.

Users are now also reporting a complete boot failure and
significant performance slowdown, which suggests that there are
some very nasty gremlins in the works.

“Had this exact issue with my PC. Was causing absolute havoc.
Couldn’t access the BIOS, couldn’t even get it to install a
fresh install of Windows as the system locked and would get
stuck in a boot cycle. By some miracle, it booted up randomly
on its literal millionth attempt and I restored back to before
the update. Hey presto, problem solved,” one user wrote in our
comment section.

“I did the update. Lost my desktop, I could see the mouse
cursor, that’s all. No response from keyboard. No way of
knowing what to click on. I finally did a system reset getting
a fresh image from the hidden partition and got my desktop and
full functionality back,” another user said.

Network problems (Bluetooth, WiFi)

Windows 10 update also knocks down the network adapters and it
slows down the performance of your wired or wireless internet
connection, according to
several reports.

It appears that there’s another bug in this update affecting
Bluetooth adapter for some folks.

“After installation of the KB4532695, I had a problem where my
surface would not reboot after the installation but it
eventually did. However, ever since installing the KB4532695,
it has affected Bluetooth & network connection. You can get it
back using the troubleshooter but still; a big headache having
to do it so often,” another user wrote in the comment section.

Audio and Sound Blaster

If you have a computer with Sound Blaster (sound cards),
installing January optional update could disable it, according
to multiple reports.

“Soundblaster was working fine and after installing this update
is not working anymore. The sound is passing through the
motherboard drive (Realtek) instead of Soundblaster. Managed to
fix it by setting the sound under Realtek… but Soundblaster is
basically useless,” a user said.

Some Windows 10 owners with other sound cards are also
experiencing audio issues, so it’s possible that the update is
not compatible with certain versions of adapters.

Installation problems

And there are complaints that Windows 10 KB4532695 fails to
install with generic error messages. According to a system
administrator, Windows 10 may have lost track of where .NET
are installed and disabling the feature before installing the
patch resolves the installation problems.

If you’re getting errors when installing cumulative updates,
you can run the following command and disable .NET feature:

  • Dism /online /Disable-Feature /FeatureName:NetFx3

You can replace ‘Disable’ with ‘Enable’ and run the new command
to reinstate the feature after the patch is installed.

Users report that uninstalling the update fixes all these
issues. If you’re not happy with the update, here’s how to
uninstall it:

  • Settings > Update & Security > Windows Update.
  • Click on ‘View update history’.
  • Click on ‘Uninstall updates’.
  • In Control Panel’s updates page, select the knowledge base
    (KB) number of the cumulative update.
  • Click ‘Uninstall’
  • Reboot the system.

It’s also worth noting that the File Explorer fixes will be
included in February’s Patch Tuesday alongside the security
fixes.

Microsoft has yet to acknowledge the new issues in the optional
update.
