Microsoft released Windows 10 updates on Tuesday to fix a
security bug reported by the United States’ National Security
Agency (NSA). Unfortunately, the Redmond, Washington tech
giant’s latest update for Windows 10 has also run into
For context, users on May 2019 Update and
November 2019 Update are getting KB4528760 and Microsoft is
shipping KB4534273 to Windows 10 version 1809. With this
month’s Patch Tuesday update, Microsoft says it has resolved
multiple security bugs.
The flaw, which was given
“important” severity rating, affects the way Windows
CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography
certificates on Windows 10. The cumulative update, which has
been released to address this vulnerability, is apparently
failing to install for some users.
According to posts on Reddit,
Microsoft’s community forum and Twitter, Windows 10 KB4528760
for both May 2019 Update and November 2019 Update is failing to
install with generic error messages, and users are apparently
“Can’t update, getting an “We could not complete the install
because an update service was shutting down” error,” a user
“There were problems installing some updates, but we’ll try
again later. 2020-01 Cumulative Update for Windows 10 Version
1909 for x64-based Systems (KB4528760) – Error 0x800f0988.
Troubleshooter, sfc, dism don’t fix error,” another user
“Ah, apparently KB4528760 is having issues with downloading, so
I wouldn’t bother with it for right now. It failed on my PC as
well,” a user confirmed the installation
issues in a tweet. Another user stated that there were problems
with Windows 10’s January 2020 update package on their PC.
Multiple users have also documented Windows 10’s January 2020
update installation issues on Microsoft’s Community forum
one angry user noting:
“The disturbing part of all of this is that it exists in the
first place. MS’s patching and updating system is fundamentally
broken and has been for 30+ years. It is extremely poorly
designed and way too fragile.”
At the time of writing, there are no reports of other issues
after installing the cumulative update. The number of reports
suggests that the installation issues are also not widespread
at the moment, but if you’re affected, you can
install the Windows 10 cumulative updated manually.
It’s also worth noting that January 2020 Patch Tuesday update
focus was on fixing the important security issues in Windows
10. Consumers and administrators are recommended to patch their
devices as soon as possible.
