Microsoft has issued its emergency security update on Monday to disable flawed Intel software that was causing some user’s computers an unplanned reboot.

The update is to plug Intel Corp’s buggy Spectre firmware patch after the chipmaker’s fix caused computers to reboot spontaneously.

The Tech gargantuan said it was rolling out an out-of-band update that specifically disables Intel’s Spectre variant 2 patches.


More than Millions of Intel’s processors had faced this security issue in which machines get stuck and starts automatic reboot or shut down. Later Intel issued this statement that not to install it.

On 22 January, Intel told customers not to install one of the security updates it had issued, as the software patch was causing more problems.

The company said it was “making progress toward identifying the root cause”.

Microsoft said its update for Windows 7, 8.1 and 10 disabled Intel’s buggy patch and stopped the rebooting issue.

“Our own experience is that system instability can in some circumstances cause data loss or corruption,” Microsoft warned in a security bulletin.

The company claimed that it had issued the unanticipated security update but in fact, Intel took time to tests, updates and expands new microcodes.

Intel is being criticized by many tech researchers for taking time to fix this issue.

Security flaws; Meltdown and Spectre were publically issued in January, which makes data on affected computers susceptible to espionage. And Intel took four weeks to update after it confirmed that its chips were affected by vulnerabilities.

Meltdown and Spectre

Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer.

The meltdown was specific to chips from Intel as well as one from Softbank Group Corp’s ARM Holdings. Spectre affected nearly every modern computing device, including ones with chips from Intel, ARM and Advanced Micro Devices.

Vulnerabilities-Meltdown and Spectre

Specter and meltdown are causing all kind of headaches for the users not because everyone is exploiting them, but actually, those patches which are auto-generated and causing instability.

“Microsoft saving the day while Intel drags its feet with incompetent patches leading not only to system instability, but also data corruption in some cases,” wrote  Artem Russakovskii, founder of the Smartphone news site Android Police.

Tech Researchers found cracks in security stemming from – better known as the chip or microchip – that caused data to be hacked which is privately stored.

Microsoft said its latest update prevented computers to reboot unexpectedly and urged affected customers to manually download it from the Microsoft Update Catalog website.

Intel says it has identified the issues behind the unexpected reboots on Broadwell and Haswell processors and is working toward releasing an update that addresses the exploits without causing random reboots and data loss.

Ivy Bridge, Sandy Bridge, Skylake, and Kaby Lake processors are also affected, and Intel says it’s “actively working on developing solutions” for those platforms too.

Microsoft is also releasing new register key for impacted devices, allowing IT admins to manually disable or enable the Spectre variant 2 protections.

Microsoft clarified there were no known reports of the security issue being used to attack computers.

Let’s hope the updates currently in development aren’t “trash” and going to add some value in Microsoft world.
