Microsoft has released another security patch against "Spectre Variant 2" bug found on Intel chips.
Microsoft has issued the update as part of its Windows Update catalog, which means you'll need to download it manually for now. "We recommend Windows customers, when appropriate, reenable the mitigation against CVE-2017-5715 when Intel reports that this unpredictable system behaviour has been resolved for your device". Microsoft is also releasing a new registry key setting for impacted devices, allowing IT admins to manually disable or enable the Spectre variant 2 protections.
The Spectre flaw affected almost every modern computing device, including those with chips from Intel, Advanced Micro Devices (AMD) and ARM Holdings.More news: Sandeep Lamichhane, the first Nepalese to get IPL contract
