More than 1,500 exhibitors, including some of the world’s leading technology brands, will set out their stalls at Computex in the capital, with 130,000 visitors expected for the five-day event.
It comes after a security update carried a bug that critically broke the security malware component of Windows.
Windows Users Beware: Microsoft Defender for Endpoint Stops Working
As per the report by The Register, the problem with Microsoft Defender for Endpoint began on Nov. 9, when the security patch was rolled out to the users of Windows Server and Windows 10 LTSC Editions.
The news outlet further pointed out the latest issue brought upon by the latest update for Windows users kills what should help both prevent and detect malware or other similar threats to the system.
That said, Microsoft announced in a known issues and notifications post that the latest issue with the Defender for Endpoint affects users of Windows Server 2019 and Windows Server 2022, which has the KB5007206 and KB5007205 installed, respectively.
To be precise, the tech giant further warned that the said users of Windows Server should expect Defender for Endpoint to “fail to start or run” on their devices.

However, Microsoft clarified that the security patch only broke the security malware apps of those who have Windows Server installed on their devices.
As such, those who are running Windows 10 on their machines are not affected by the latest issue.
