Windows 10 users were asked last week to install a new update to the Microsoft which fixes a serious problem with this operating system. The critical bug was detected by the US National Security Agency, which said it had discovered the vulnerability in Windows that could allow attackers to defeat trusted network connections and deliver executable code while appearing to be legitimately trusted entities.
In a publication on its website, the National Security Agency said: "The NSA assesses the vulnerability as serious and that sophisticated cyber actors will understand the underlying flaw very quickly.
"The NSA recommends installing all Patch Tuesday patches for January 2020 as soon as possible to effectively reduce vulnerability across Windows 10."
Microsoft responded very quickly to the warning by promoting an update to the Windows 10 operating system, but it appears that a version is causing problems for some users when trying to install it.
KB4528760 is now available for download and includes numerous changes, but several Windows fans have accessed Reddit, Twitter and even Microsoft's forums to complain about problems.
It appears that when trying to update to certain devices, some are seeing the error message: "There was a problem installing some updates, but we will try again later. Cumulative update 2020-01 for Windows 10 version 1909 for based systems x64 (KB4528760) – Error 0x800f0988. The troubleshooter, sfc, dism does not fix the error "
There were also mentions of problems for those who managed to install KB4528760 with a user saying, "This update has interrupted my audio".
And another added: "This update made my laptop run at about a twentieth the speed it should be and Chrome doesn't respond."
It is not clear how serious this installation bug is or how many people are affected by it with Microsoft currently saying on its website that there are no known issues with KB4528760.
If you haven't updated your PC yet, it seems pretty clear that you should try to download this patch as soon as possible.
For those who are unable to safely load this update on their PCs, it is a worrying time as it means that their machines are not protected against the latest threats.
Fortunately, Microsoft will release advice or a new patch in the coming days and Express.co.uk will update this story if we know more.
It is worth mentioning that if you have Windows 7 installed, it is unlikely that this update will be available for your device.
Microsoft officially ended support for this operating system last week, which means that, as of now, it will not offer new updates or bug fixes.
Advice on the Windows 7 support page, Microsoft says: "For most Windows 7 users, moving to a new device with Windows 10 will be the recommended way. Today's PCs are faster, lighter, but powerful and more secure, with an average price this is considerably less than the average PC eight years ago. We recommend that you do not install Windows 10 on an older device, as some Windows 7 devices are not compatible with Windows 10 or may have reduced availability of resources ".
